Final answer:
Energy exists in various forms, and the kinetic energy of a body depends on its mass and velocity.
Explanation:
Forms of Energy: Energy exists in various forms such as light, chemical, heat, kinetic, and potential energy.
Kinetic Energy Factors: The kinetic energy of a body depends on its mass and velocity. A larger mass or higher velocity results in greater kinetic energy.
Examples: A truck with more mass moving at a higher velocity will have more kinetic energy than a lighter car moving at the same speed.
