Force, energy, motion review

Front

What is force?

Back

A push or pull on an object that can cause it to move, stop, or change direction.

Front

What is kinetic energy?

Back

The energy an object has due to its motion.

Front

What is potential energy?

Back

The energy stored in an object because of its position or state.

Front

What is gravity?

Back

A force that pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

What is inertia?

Back

The tendency of an object to stay at rest or to keep moving in a straight line unless acted upon by a force.

Front

What happens when two forces are balanced?

Back

The object remains at rest or continues to move at a constant speed in a straight line.

Front

What happens when forces are unbalanced?

Back

The object will accelerate in the direction of the greater force.

Front

How does mass affect potential energy?

Back

The more mass an object has, the more potential energy it has when elevated.

Front

What is the relationship between height and potential energy?

Back

The higher an object is, the more potential energy it has.

Front

What is the effect of incline on kinetic energy?

Back

Changing the incline of a ramp can increase or decrease the speed of an object, thus affecting its kinetic energy.
