1. What is kinetic energy?
Kinetic energy is the energy possessed by an object due to its motion. It can be calculated by the equation KE = 1/2mv^2, where m is the mass of the object and v is its velocity.
2. What is potential energy?
Potential energy is the energy possessed by an object due to its position or state. It can exist in various forms such as gravitational potential energy, elastic potential energy, chemical potential energy, etc.
3. What are some examples of kinetic energy?
Examples of kinetic energy include a moving car, a rolling ball, a flying bird, a person running, etc.
4. What are some examples of potential energy?
Examples of potential energy include a book on a shelf, a stretched spring, water stored in a dam, a compressed gas cylinder, etc.
5. How can kinetic energy be converted into potential energy?
Kinetic energy can be converted into potential energy when an object is lifted against gravity, such as when throwing a ball upwards. As the ball rises, its kinetic energy decreases and potential energy increases until it reaches its maximum height, where all the kinetic energy is converted into potential energy.
