Front

Back

the amount of matter in an object

Front

Which type of force(s) will cause a change in an object's motion?

Back

unbalanced forces

Front

If all of the objects have the same acceleration, which will require the greatest force?

Back

The object with the greatest mass.

Front

Pushing a child on a swing is easier than pushing an adult on the same swing, because the adult has more mass. This relates to which of Newton's Laws?

Back

Newton's 2nd Law

Front

The sum of all the forces that are acting on an object is called _____

Back

Net Force

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 a net external force.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m x a)

Front

What is friction?

Back

A force that opposes the motion of an object.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces do.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.
