Front

What is the standard unit force is measured in?

Back

Newtons

Front

What force does a chair exert on a student weighing 500 newtons?

Back

500 newtons

Front

What does a position vs. time graph indicate if the object is accelerating?

Back

The object is speeding up.

Front

What law of motion states that for every action, there is an equal and opposite reaction?

Back

Newton's 3rd law.

Front

What term describes a 'push or pull'?

Back

Force

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma)

Front

What is inertia?

Back

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

Front

What does Newton's 1st law state?

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 relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass (Weight = mass × gravity).

Front

What is acceleration?

Back

The rate of change of velocity of an object.
