*The change in momentum in a collision is determined by subtracting the initial momentum from the final momentum. In an elastic collision, both momentum and kinetic energy are conserved. In an inelastic collision, momentum is conserved, but kinetic energy is lost. In perfectly inelastic collisions, objects stick together, and in completely inelastic collisions, they collide and stick together while losing kinetic energy.*

**3. What is the formula for the change in momentum of an elastic collision?** In an elastic collision, the formula for the change in momentum is the same as in any collision: Δp = p_final – p_initial.

**4. What is the formula for calculating change in momentum?** The formula for calculating change in momentum is: Δp = p_final – p_initial.

**5. How do you solve momentum collision problems?** To solve momentum collision problems, you typically follow these steps: a. Calculate the initial and final momenta of the objects involved. b. Apply the law of conservation of momentum (for elastic collisions) or use other relevant information to determine the final velocities. c. Use the appropriate equations to find the desired quantities (e.g., final velocities, masses, etc.).

**6. How do you find the momentum of two objects before a collision?** You find the momentum of two objects before a collision by multiplying each object’s mass (m) by its initial velocity (v): Momentum = m1 * v1 + m2 * v2.

**7. What is the change in momentum?** Change in momentum (Δp) is the difference between the final momentum and the initial momentum of an object or system.

**8. What will be the total momentum of the objects before and after collision?** In the absence of external forces, the total momentum of the objects before a collision will be equal to the total momentum of the objects after the collision. This is described by the law of conservation of momentum.

**9. What is the change in momentum after an inelastic collision?** In an inelastic collision, the change in momentum is still given by Δp = p_final – p_initial, but unlike in an elastic collision, kinetic energy is not conserved, so some of the initial kinetic energy is lost as internal energy.

**10. What is collision formula?** There isn’t a single “collision formula,” as the calculations depend on the type of collision (elastic or inelastic) and the specific quantities you want to find. However, the fundamental formula is Δp = p_final – p_initial.

**11. How to find the momentum of two objects after an elastic collision?** To find the momenta of two objects after an elastic collision, you need to use the law of conservation of momentum and kinetic energy. The equations can be quite complex, involving variables like masses and initial velocities.

**12. What is momentum during a collision?** Momentum during a collision refers to the momentum possessed by objects or a system of objects before and after the collision occurs.

**13. What is an example of momentum in a collision?** An example of momentum in a collision is two billiard balls colliding on a pool table. Before the collision, each ball has its own momentum, and after the collision, the momenta of the balls change as a result of the collision.

**14. What is the formula for linear momentum and collision?** Linear momentum (p) is calculated by multiplying an object’s mass (m) by its velocity (v): p = m * v. For collisions, the change in momentum is often used: Δp = p_final – p_initial.

**15. What is the momentum of the two cars after the collision?** To find the momentum of two cars after a collision, you’d need information about their masses and velocities before and after the collision. The momentum of each car can be calculated as p = m * v.

**16. How do you find the change of momentum for a single object after a collision?** The change in momentum for a single object after a collision is found by subtracting its initial momentum from its final momentum: Δp = p_final – p_initial.

**17. What is the formula for initial and final momentum?** The formulas for initial (p_initial) and final (p_final) momentum are the same: p = m * v, where m is mass and v is velocity.

**18. Does momentum change in an elastic collision?** In an elastic collision, momentum is conserved, which means the total momentum of the system remains constant. However, individual object momenta can change direction and magnitude.

**19. Is the total momentum before the collision zero?** The total momentum before a collision is not necessarily zero. It depends on the initial velocities and masses of the objects involved.

**20. What is the total momentum of the carts after the collision?** The total momentum of the carts after a collision can be calculated by summing the momenta of each cart after the collision.

**21. Why is momentum lost in a collision?** Momentum is not lost in a collision; it is conserved. However, in an inelastic collision, some initial kinetic energy may be transformed into other forms of energy, making it seem like “momentum is lost.”

**22. How do you calculate collision force?** Collision force can be calculated using the impulse-momentum theorem: Force = Δp / Δt, where Δp is the change in momentum and Δt is the time over which the collision occurs.

**23. What is the total momentum of the system before collision?** The total momentum of the system before a collision is the sum of the momenta of all objects involved.

**24. Is momentum always conserved?** In isolated systems (where there are no external forces), momentum is always conserved. This is known as the law of conservation of momentum.

**25. How to find the final velocity of two objects after an elastic collision?** To find the final velocities of two objects after an elastic collision, you’ll need information about their masses and initial velocities. You can use equations that involve conservation of both momentum and kinetic energy.

**26. How do you calculate momentum after an inelastic collision?** To calculate momentum after an inelastic collision, you still use the basic momentum formula (p = m * v), but in an inelastic collision, kinetic energy is not conserved, so some of the initial kinetic energy is lost as internal energy.

**27. What is the formula for elastic collision and inelastic collision?** In an elastic collision, both momentum and kinetic energy are conserved. In an inelastic collision, momentum is conserved, but kinetic energy is not. There isn’t a single formula; the specific equations depend on the details of the collision.

**28. What is the formula for after collision?** The formula for after the collision depends on what specific quantity you want to calculate. Generally, you use principles of conservation of momentum and energy to derive equations for the final velocities or momenta of objects after a collision.

**29. How do momentum and collisions work?** Momentum is a property of moving objects, and it is conserved in collisions. In a collision, objects may exchange momentum, but the total momentum of the system remains constant if no external forces are involved.

**30. What are the three types of momentum collisions?** The three types of momentum collisions are: 1. Elastic Collision: Both momentum and kinetic energy are conserved. 2. Inelastic Collision: Momentum is conserved, but kinetic energy is not. 3. Perfectly Inelastic Collision: A type of inelastic collision where objects stick together after the collision.

**31. What are 3 examples of momentum?** Three examples of momentum are: 1. A moving car on a highway. 2. A baseball pitched by a pitcher. 3. A person running.

**32. What is the basic equation for momentum?** The basic equation for momentum is: Momentum (p) = mass (m) × velocity (v).

**33. What is the relationship between momentum and collision?** The relationship between momentum and collision is that momentum is conserved in collisions, meaning the total momentum of a system of objects remains constant unless external forces are present.

**34. What is a collision in which linear momentum is conserved?** A collision in which linear momentum is conserved is known as an “elastic collision.” In an elastic collision, both momentum and kinetic energy are conserved.

**35. How do you find the final momentum of an object?** To find the final momentum of an object, multiply its mass by its final velocity: p_final = m * v_final.

**36. Is initial momentum always equal to final momentum?** No, initial momentum is not always equal to final momentum. They can be equal in certain situations where no external forces are acting, but in many cases, they are not equal due to the exchange of momentum during a collision.

**37. Is change in momentum final minus initial?** Yes, the change in momentum (Δp) is calculated by subtracting the initial momentum from the final momentum: Δp = p_final – p_initial.

**38. How is the change in momentum zero?** The change in momentum is zero when the final momentum is equal to the initial momentum, meaning there has been no net change in momentum during the process.

**39. When is the total change in momentum zero?** The total change in momentum is zero when the total initial momentum of a system is equal to the total final momentum, which often occurs in isolated systems.

**40. Is the total momentum always constant in any collision crash?** The total momentum is always constant in any collision as long as no external forces are acting on the system. This is a fundamental principle known as the law of conservation of momentum.

**41. What does it mean if the total momentum was negative?** If the total momentum is negative, it means that the objects in the system are moving in a direction opposite to the chosen reference direction. Momentum is a vector quantity, so it has both magnitude and direction.

**42. Is the total momentum the same after collision?** In the absence of external forces, the total momentum before a collision is equal to the total momentum after the collision. This is a consequence of the law of conservation of momentum.

**43. Does momentum change in a car crash?** Momentum is conserved in a car crash, assuming no external forces are involved. However, the distribution of momentum among the vehicles involved can change significantly due to the collision.

**44. What are the 4 types of collisions?** The four types of collisions are: 1. Elastic Collision: Both momentum and kinetic energy are conserved. 2. Inelastic Collision: Momentum is conserved, but kinetic energy is not. 3. Perfectly Inelastic Collision: A type of inelastic collision where objects stick together after the collision. 4. Completely Inelastic Collision: A variation of inelastic collision where objects collide and stick together, but kinetic energy is not conserved.
