Front

Front

When something has speed in a certain direction it is called ___________.

Back

velocity

Front

What does a graph representing constant velocity look like?

Back

A straight line with a constant slope.

Front

What is Newton's Third Law?

Back

For every action there is an equal and opposite reaction.

Front

Which force produces a change in motion?

Back

unbalanced force

Front

What is the formula for calculating force?

Back

Force = mass x acceleration

Front

What is inertia?

Back

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

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is acceleration?

Back

The rate of change of velocity over time.

Front

What is the law of universal gravitation?

Back

Every point mass attracts every other point mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
