**19. What is tangential acceleration and its formula?** Tangential acceleration is the acceleration of an object along its curved path. Its formula is a_t = d(v)/dt, where ‘a_t’ is tangential acceleration, and ‘d(v)/dt’ is the derivative of velocity with respect to time.

**20. How to find tangential and normal acceleration of a point moving in a plane curve?** Tangential acceleration is found using the formula a_t = d(v)/dt, and normal acceleration is found using a = (v^2) / r, where ‘v’ is velocity and ‘r’ is the radius of curvature of the curve.

**21. Is normal vector parallel or perpendicular?** A normal vector is perpendicular to the surface or curve at a specific point. It is, by definition, orthogonal to the tangent direction.

**22. What is meant by tangential acceleration?** Tangential acceleration is the acceleration that changes the magnitude of an object’s velocity as it moves along a curved path. It is directed along the tangent to the path.

**23. Is tangential acceleration always parallel to velocity?** Yes, tangential acceleration is always parallel to the velocity because it affects the speed or magnitude of the velocity vector while keeping its direction along the tangent to the path.

**24. What is the formula for tangent vector and normal vector?** The formula for the tangent vector is based on the derivative of the position vector with respect to time, while the formula for the normal vector depends on the specific geometry of the surface or curve and involves taking derivatives or gradients.

**25. What is the normal vector of a line in vector form?** The normal vector of a line in vector form can be obtained by taking the direction vector of the line and finding a vector that is perpendicular to it. This can often be done by flipping the components and changing the sign of one of them.

**26. What are normal and parallel vectors?** Normal vectors are vectors that are perpendicular to a given surface or curve, while parallel vectors are vectors that have the same direction.

**27. What is normal acceleration always perpendicular to?** Normal acceleration is always perpendicular to the velocity vector in the context of circular motion.

**28. What is the difference between tangential and normal?** Tangential refers to the direction parallel to the motion, while normal refers to the direction perpendicular to the motion.

**29. Is tangential acceleration the same as rotational acceleration?** No, tangential acceleration and rotational acceleration are not the same. Tangential acceleration is related to changes in speed along a curved path, while rotational acceleration is associated with changes in angular velocity in rotational motion.

**30. Is normal acceleration negative?** Normal acceleration can be positive or negative, depending on whether an object is speeding up or slowing down along a curved path.

**31. Is radial acceleration linearly proportional to the rotational acceleration?** Radial acceleration is not linearly proportional to rotational acceleration. Their relationship depends on the specific geometry of the circular motion and can involve various factors.

**32. What is the relationship between radial and transverse acceleration?** Radial acceleration is synonymous with centripetal acceleration and is directed toward the center of a circular path. Transverse acceleration is a general term for acceleration perpendicular to the velocity, which can include both radial and normal acceleration.

**33. Why is tangential acceleration opposite to velocity?** Tangential acceleration can be opposite to velocity when an object is slowing down along its curved path. It acts to decrease the speed or magnitude of the velocity vector.

**34. Why does tangential acceleration change with radius?** Tangential acceleration changes with radius because it is inversely proportional to the radius in circular motion. As the radius increases, the tangential acceleration decreases, and vice versa.

**35. Does constant speed mean no tangential acceleration?** Yes, if an object is moving at a constant speed, it means there is no tangential acceleration. Tangential acceleration only exists when the speed or magnitude of velocity is changing.

**36. What is the difference between radial and tangential acceleration?** Radial acceleration (centripetal acceleration) is directed toward the center of the circular path and is responsible for keeping an object in circular motion. Tangential acceleration is parallel to the tangent of the path and changes the speed of the object along the path.

**37. What are the different types of accelerations in circular motion?** In circular motion, there are mainly two types of accelerations: tangential acceleration, which changes the speed, and radial acceleration (centripetal acceleration), which changes the direction of velocity toward the center of the circle.

**38. How to distinguish between centripetal acceleration and centrifugal acceleration?** Centripetal acceleration is the acceleration directed toward the center of a circular path. There is no such thing as “centrifugal acceleration.” Instead, the sensation of being pushed outward in a rotating reference frame is due to inertia, not an actual acceleration.

**39. Is the acceleration vector tangent to the circle?** No, the acceleration vector in circular motion is not always tangent to the circle. It has two components: a tangential component and a radial (centripetal) component.

**40. What is acceleration vector in uniform circular motion always?** In uniform circular motion, the acceleration vector is always directed toward the center of the circle. It is purely radial (centripetal) and does not have a tangential component.

**41. How do you find the acceleration vector from a velocity vector?** To find the acceleration vector from a velocity vector, you need additional information about the motion, such as the curvature of the path or the time rate of change of velocity.

**42. Can norm of a vector be less than 1?** Yes, the norm (magnitude) of a vector can be less than 1. In fact, the magnitude of a vector can be any positive real number or zero.

**43. What if normal vector is zero?** If the normal vector is zero, it means there is no well-defined surface or direction perpendicular to the surface at that point.

**44. What does it mean for a vector to have norm 1?** A vector with a norm (magnitude) of 1 is called a unit vector. It represents a direction without changing the scale or magnitude of other vectors when used for scaling.

**45. Why are normal vectors called normal?** Normal vectors are called “normal” because they are perpendicular (normal) to the surface or curve at a specific point.

**46. What is the purpose of a normal vector?** The purpose of a normal vector is to describe the orientation or direction perpendicular to a surface or curve at a given point. It is commonly used in physics, mathematics, and computer graphics to calculate angles, reflections, and surface properties.

**47. What is the difference between a normal vector and a direction vector?** A normal vector is perpendicular to a surface or curve, while a direction vector indicates a specific direction in space. They serve different purposes and have different applications.

**48. What is the general equation for the normal vector?** The general equation for the normal vector depends on the specific mathematical representation of the surface or curve and is not a single fixed formula. It involves taking derivatives or gradients of the equation describing the surface or curve.

**49. How do you find the normal vector in physics?** In physics, the normal vector is often found by taking the derivative or gradient of the equation describing the surface or curve at a specific point. The method varies depending on the problem’s context and mathematical representation.

**50. How to calculate acceleration?** Acceleration can be calculated using the formula a = Î”v/Î”t, where ‘a’ is acceleration, Î”v is the change in velocity, and Î”t is the change in time. Alternatively, it can be calculated as the derivative of velocity with respect to time, a = dv/dt.
