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 can be gravitational, elastic, or chemical.

Front

Where is gravitational potential energy highest?

Back

Gravitational potential energy is highest at the highest point in a gravitational field, such as the top of a hill or a cliff.

Front

What factors affect Kinetic Energy?

Back

Kinetic Energy is affected by the mass of the object and the square of its velocity (KE = 1/2 mv²).

Front

What is the formula for Potential Energy?

Back

The formula for gravitational potential energy is PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

How does height affect Potential Energy?

Back

As the height of an object increases, its gravitational potential energy increases, assuming mass remains constant.

Front

What happens to Kinetic Energy when speed doubles?

Back

If the speed of an object doubles, its Kinetic Energy increases by a factor of four, since KE is proportional to the square of the velocity.

Front

What is an example of Kinetic Energy in everyday life?

Back

A moving car, a flowing river, or a person running are all examples of Kinetic Energy.

Front

What is an example of Potential Energy?

Back

A drawn bow, a compressed spring, or a rock perched at the edge of a cliff are examples of Potential Energy.

Front

What type of energy does a falling object have just before it hits the ground?

Back

Just before hitting the ground, a falling object has maximum Kinetic Energy and minimum Potential Energy.
