Force and Motion Review 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 is Newton's 1st 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 Newton's 2nd Law of Motion?

Back

The acceleration of an object depends on the mass of the object and the amount of force applied (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is net force?

Back

The total force acting on an object after all the forces are combined.

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 a change in motion.

Front

What is friction?

Back

A force that opposes the motion of an object, acting in the opposite direction.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) x acceleration (a).
