Energy, Forces, and Motion Review

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion. The faster an object moves, the more kinetic energy it has.

Front

What is potential energy?

Back

Potential energy is stored energy that has the potential to do work. It is energy based on an object's position or state.

Front

What forces slow down a water rocket when going up?

Back

Both friction and gravity slow down a water rocket when it is ascending.

Front

Which letter shows the ball when it has the least kinetic energy?

Back

A shows the ball when it has the least kinetic energy.

Front

What is the relationship between kinetic energy and potential energy?

Back

Kinetic energy and potential energy are forms of mechanical energy. As one increases, the other typically decreases in a closed system.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It acts between surfaces in contact.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

How does height affect potential energy?

Back

The higher an object is, the more potential energy it has due to its position relative to the ground.

Front

What happens to kinetic energy as an object slows down?

Back

As an object slows down, its kinetic energy decreases.

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.
