Back

10 N, to the left.

Front

What type of forces cause a change in an object's motion?

Front

What is the term for an object's resistance to a change in its motion?

Back

Inertia.

Front

Define net force.

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 and how does it affect motion?

Back

Inertia is the tendency of an object to resist changes in its state of motion; it affects how easily an object can be set in motion or stopped.

Front

What is the formula for calculating net force?

Back

Net force = Force applied - Force opposing.
