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 the square of its velocity.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy of an object due to its position or state. It is often associated with gravitational energy when an object is at a height.

Front

At which point is potential energy greatest in a swing?

Back

At the highest point of the swing.

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

What is the formula for Kinetic Energy?

Back

The formula for Kinetic Energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for Potential Energy?

Back

The formula for Potential Energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

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, while potential energy is highest at the highest points.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be caused by a change in speed or direction.

Front

What does Newton's 3rd law of motion state?

Back

Newton's 3rd law states that for every action, there is an equal and opposite reaction.

Front

How does height affect potential energy?

Back

The higher an object is, the greater its potential energy due to the increased height in the gravitational field.
