Force and Motion Review

Front

What is force?

Back

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

Front

What is motion?

Back

The change in position of an object over time.

Front

What is frictional force?

Back

A force that opposes the motion of an object, caused by the contact between two surfaces.

Front

What is gravitational force?

Back

The attractive force between two masses, such as the Earth and an object.

Front

What is average speed?

Back

The total distance traveled divided by the total time taken.

Front

What is acceleration?

Back

The rate at which an object changes its velocity, which can be an increase or decrease in speed.

Front

What is the normal force?

Back

The support force exerted by a surface perpendicular to the object resting on it.

Front

What is a constant speed?

Back

When an object covers equal distances in equal intervals of time.

Front

What is variable speed?

Back

When an object's speed changes over time.

Front

What is Newton's second law of motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
