Force & Motion Test Study Guide

Front

What does a position vs. time graph indicate when an object is accelerating?

Back

The object is changing its speed over time, indicating that its velocity is increasing.

Front

What is Newton's Second Law of Motion?

Back

It states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What unit is force measured in?

Back

Newtons (N).

Front

How can you tell if an object is speeding up on a graph?

Back

If the slope of the position vs. time graph is increasing, the object is speeding up.

Front

What does Newton’s Third Law of Motion state?

Back

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

Front

What is the relationship between mass and acceleration when the same force is applied?

Back

An object with less mass will accelerate more than an object with more mass when the same force is applied.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma).

Front

What happens to the motion of an object if no net force acts on it?

Back

The object will remain at rest or continue to move at a constant velocity.

Front

What is the effect of friction on motion?

Back

Friction opposes the motion of an object, causing it to slow down or stop.
