Question: Define work power and energy with their units?

Work, power and energy are important concepts in physics. Work is the application of force to move an object over a distance in the direction of the force. The unit of work is joule (J), which is equal to newton-meter (N⋅m) or kilogram-meter-squared per second-squared (kg⋅m^2/s^2). Power is the rate at which work is done or energy is transferred. The unit of power is watt (W), which is equal to joule per second (J/s) or kilogram-meter-squared per second-cubed (kg⋅m^2/s^3). Energy is the ability to do work or cause change. Energy can be stored as potential energy or transferred as kinetic energy. The unit of energy is also joule (J). Potential energy is the stored energy an object has due to its position or condition. For example, a rock lifted above the ground has gravitational potential energy. Kinetic energy is the energy of motion. For example, a moving car has kinetic energy.
