Force and Motion 8th grade

Front

What is Force?

Back

A push or pull on an object that can cause it to change its motion.

Front

What is Motion?

Back

The change in position of an object over time.

Front

What are Balanced Forces?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are Unbalanced Forces?

Back

Forces that are not equal and can cause an object to move or change its motion.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

Front

What is the equation for Force?

Back

Force = mass x acceleration (F = ma).

Front

What is Net Force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

What happens when the net force is zero?

Back

The object remains at rest or continues to move at a constant velocity.

Front

What is Friction?

Back

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

Front

What is Acceleration?

Back

The rate at which an object changes its velocity.
