Force and Motion

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 until acted upon by an unbalanced force.

Front

What is the definition of velocity?

Back

The measurement of speed and direction of an object.

Front

What units are used to measure force?

Back

Newtons.

Front

What is average speed?

Back

The overall speed of an object during the entire course of a trip.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is the difference between speed and velocity?

Back

Speed is how fast an object is moving, while velocity includes both speed and direction.

Front

What is acceleration?

Back

The rate of change of velocity of an object.

Front

What is the formula for calculating force?

Back

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

Front

What is inertia?

Back

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

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass.
