Kinetic and Potential Energy Review

Front

What is the difference between kinetic energy and potential energy?

Back

Kinetic energy is the energy of an object in motion, while potential energy is the stored energy of an object due to its position or state.

Front

What happens to potential energy as an object descends?

Back

Potential energy is converted into kinetic energy as the object descends.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy is KE = 1/2 mv², where m is mass and v is velocity.

Front

How does mass affect kinetic energy?

Back

Increasing an object's mass will increase its kinetic energy, assuming velocity remains 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 as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What type of energy does a person climbing a ladder possess?

Back

A person climbing a ladder possesses both kinetic energy (due to movement) and potential energy (due to height gained).

Front

What is the relationship between height and potential energy?

Back

Potential energy increases with height; the higher an object is, the more potential energy it has.

Front

What is the unit of energy in the International System of Units (SI)?

Back

The unit of energy in the SI system is the Joule (J).

Front

What is an example of kinetic energy in everyday life?

Back

An example of kinetic energy is a moving car, a running athlete, or a flowing river.

Front

What happens to the total mechanical energy of a system if only conservative forces are acting?

Back

The total mechanical energy of a system remains constant if only conservative forces (like gravity) are acting.
