Force and Motion - Unit Test Review

Front

What is net force?

Back

The overall force acting on an object when all the individual forces are combined. If forces are in the same direction, they are added together.

Front

How do you find the net force when two forces are acting in the same direction?

Back

Add the magnitudes of the two forces.

Front

What is the unit of force?

Back

Newton (N)

Front

What is the formula for calculating force?

Back

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

Front

What is acceleration?

Back

The rate of change of velocity of an object.

Front

What is the unit of acceleration?

Back

Meters per second squared (m/s²)

Front

What does a flat line on a distance-time graph represent?

Back

No motion.

Front

What does a steep slope on a distance-time graph indicate?

Back

A high speed.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate.

Front

What is inertia?

Back

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