Kinetic and Potential Energy

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 is often associated with gravitational energy when an object is elevated.

Front

At which point is potential energy greatest in a gravitational field?

Back

Potential energy is greatest at the highest point in a gravitational field.

Front

What type of energy does a rock at the edge of a cliff have?

Back

The rock has potential energy because it is elevated above the ground.

Front

Where is gravitational potential energy minimum?

Back

Gravitational potential energy is minimum at the lowest point, such as in a basement.

Front

What is the formula for calculating Kinetic Energy?

Back

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

Front

What is the formula for calculating Potential Energy?

Back

Potential Energy (PE) = mass (m) * gravitational acceleration (g) * height (h).

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

Can an object have both kinetic and potential energy?

Back

Yes, an object can have both types of energy, such as a swinging pendulum.

Front

What is an example of kinetic energy in everyday life?

Back

A moving car, a running person, or a flowing river are all examples of kinetic energy.
