Kinetic and Potential Energy Practice

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, calculated using the formula KE = 1/2 mv².

Front

What is Potential Energy?

Back

Potential Energy is stored energy based on an object's position or state. It can be gravitational, elastic, or chemical energy.

Front

What is the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What type of energy does a roller coaster have at the top of a hill?

Back

At the top of a hill, a roller coaster has high potential energy due to its elevated position.

Front

What type of potential energy is associated with a stretched rubber band?

Back

A stretched rubber band has Elastic Potential Energy.

Front

How does kinetic energy change as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, maintaining the total energy constant.

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the energy an object possesses due to its height above the ground, calculated using the formula PE = mgh.

Front

What happens to potential energy when an object is lifted higher?

Back

When an object is lifted higher, its gravitational potential energy increases.

Front

What is the relationship between kinetic and potential energy in a pendulum?

Back

In a pendulum, kinetic energy is highest at the lowest point of the swing, while potential energy is highest at the highest points of the swing.

Front

What is an example of a situation where energy is transformed from potential to kinetic?

Back

An example is a ball rolling down a hill; as it descends, its potential energy converts to kinetic energy.
