Energy Transformations

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass of the object and its velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It can be gravitational, elastic, or chemical.

Front

What is the relationship between kinetic and potential energy?

Back

Kinetic and potential energy are forms of mechanical energy. As an object moves, energy can transform from potential to kinetic and vice versa.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object has due to its height above the ground. It is calculated as weight times height.

Front

How does energy transfer when a ball is dropped?

Back

As the ball falls, potential energy is converted into kinetic energy until it reaches the ground.

Front

What happens to kinetic energy when a car accelerates?

Back

As a car accelerates, its speed increases, which increases its kinetic energy.

Front

What is an example of potential energy?

Back

A book on a shelf has potential energy because of its height above the ground.

Front

What is an example of kinetic energy?

Back

A wagon rolling down a hill is an example of kinetic energy because it is in motion.

Front

How can energy transformations be observed in a bouncing ball?

Back

In a bouncing ball, energy transforms from potential energy at the highest point to kinetic energy as it falls, and back to potential energy at the peak of each bounce.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 * mass (m) * velocity (v)².
