Front

Fill in the blank: ________ is the measurement of the total forces exerted on an object, measured in Newtons (N).

Back

Net force

Front

Newton's 1st law is the tendency of an object to resist change in motion unless acted upon by ________.

Back

an outside net force

Front

Newton's 2nd law states that when an object that has a constant mass is acted upon by a force, the object will accelerate in the same direction as the ________ applied.

Back

force

Front

Newton's 3rd law states that for every action, there is an equal and opposite ________.

Back

reaction

Front

Fill in the blank: ________ is the process or effect produced by an agent, substance, or force that causes a change in a system or organism.

Back

Action

Front

Fill in the blank: ________ are equal and opposite forces on an object that result in no change in position, direction, or motion; combined net force equals zero.
