**What is the PE = 1/2kx^2?** The formula PE = 0.5 * k * x^2 represents the potential energy stored in a spring that is compressed or stretched. “k” is the spring constant, and “x” is the displacement from the equilibrium position.

**What is total mechanical energy?** Total mechanical energy is the sum of an object’s potential energy and kinetic energy. It represents the combined energy of an object due to its position and motion.

**What is the formula for energy?** The formula for energy depends on the type of energy you’re considering. For mechanical energy, it’s ME = PE + KE. The general formula for energy is E = P * t, where E is energy, P is power, and t is time.

**What is mechanical energy in physics?** Mechanical energy in physics refers to the sum of an object’s potential energy and kinetic energy. It’s the energy associated with an object’s position and motion.

**What is mechanical energy in physics?** Mechanical energy in physics refers to the sum of potential energy and kinetic energy possessed by an object due to its position and motion.

**What is the formula for mechanical energy to heat energy?** The conversion of mechanical energy to heat energy involves the concept of work-energy theorem and friction. Mechanical energy lost due to work done against friction is converted into heat energy.

**How do you calculate total mechanical energy?** Total mechanical energy is calculated by adding an object’s potential energy and kinetic energy: ME = PE + KE.

**Is total mechanical energy always 0?** No, total mechanical energy is not always 0. In the absence of external forces like friction, the total mechanical energy of a closed system remains constant due to the conservation of energy.

**How do you calculate energy in physics?** Energy can be calculated using various formulas depending on the type of energy you’re considering. For mechanical energy, it’s ME = PE + KE. For other types, such as thermal energy, it might involve different equations.

**What is mechanical energy for kids?** Mechanical energy for kids refers to the energy an object has due to its movement or position. It’s a combination of potential energy and kinetic energy.

**What is the formula for energy in physics GCSE?** For GCSE physics, the formula for mechanical energy is: ME = PE + KE, where ME is mechanical energy, PE is potential energy, and KE is kinetic energy.

**What does c stand for in E=mc^2?** In the equation E=mc^2, “c” stands for the speed of light in a vacuum, which is approximately 3 x 10^8 meters per second.

**What does K mean in physics?** In physics, “K” can represent various quantities, such as the spring constant (k) in Hooke’s law, the kinetic energy (KE) of an object, or the Kelvin temperature scale.

**What is K in potential energy?** In potential energy formulas, “K” often represents a constant, such as the spring constant (k) in the potential energy stored in a spring (PE = 0.5 * k * x^2).

**Why was Hooke’s law negative?** Hooke’s law is not inherently negative. It describes the relationship between the force exerted by a spring and its displacement from equilibrium. The negative sign indicates that the force exerted by the spring is opposite to the direction of displacement.

**What are the units in joules?** Joules (J) are the units of energy and work in the International System of Units (SI).

**What unit is K in spring?** The spring constant “k” in Hooke’s law is typically expressed in units of newtons per meter (N/m) or pascals (Pa), depending on the context.

**Why is potential energy 1/2kx^2?** The formula PE = 0.5 * k * x^2 represents the potential energy stored in a spring that is compressed or stretched. The factor of 0.5 comes from the integration of the force applied by the spring over its displacement.

**Why a stone on the ground has zero energy?** A stone on the ground has gravitational potential energy relative to a reference point (like the ground). However, if you consider the ground as the reference point, the stone has zero potential energy and only kinetic energy if it’s in motion.

**Which two types of energy does an apple falling to the ground have?** An apple falling to the ground has both potential energy (while it’s elevated) and kinetic energy (while it’s in motion).

**What is an object having the capacity to do work is said to be?** An object having the capacity to do work is said to possess energy.

**How many watts is a joule?** One joule (J) is equal to one watt-second (Ws). The watt is the unit of power, and one watt is equal to one joule of energy per second.

**What is a particle of electromagnetic radiation known as?** A particle of electromagnetic radiation is known as a photon.

**How do you find the current in a circuit?** The current (I) in a circuit can be calculated using Ohm’s law: I = V / R, where V is voltage and R is resistance.

**Is there a formula for energy?** Yes, there are various formulas for different types of energy, depending on the context. For example, mechanical energy is calculated using ME = PE + KE.

**What is the energy calculator?** An energy calculator is a tool or formula used to calculate the amount of energy associated with a particular system or process.

**What is the real formula of energy?** The formula for energy depends on the type of energy you’re considering. For mechanical energy, it’s ME = PE + KE. Other forms of energy have their own specific formulas.

**What does E=mc^2 mean for kids?** For kids, E=mc^2 means that energy (E) is equal to the mass (m) of an object multiplied by the speed of light (c) squared. It’s a famous equation from Albert Einstein’s theory of relativity.

**What is the E=mc^2 for dummies?** “E=mc^2 for dummies” is a simplified explanation of Einstein’s mass-energy equivalence equation. It means that energy is equal to mass times the speed of light squared.

**Who disproved E=mc^2?** E=mc^2 has not been disproven. It is a fundamental equation in physics, supported by extensive experimental evidence.
