Newton's Laws of Motion Review

Front

What is Newton's First Law of Motion?

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 Newton's Second Law of Motion?

Back

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 is Newton's Third Law of Motion?

Back

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

Front

What unit is force measured in?

Back

Newtons (N).

Front

How do you calculate force according to Newton's Second Law?

Back

Multiply mass (kg) by acceleration (m/s²).

Front

What happens to a bowling ball when it strikes a bowling pin?

Back

The force applied by the pin to the ball is equal to the force applied by the ball.

Front

If a football player has a mass of 300 kg and accelerates at 2 m/s², how much force does he exert?

Back

600 Newtons.

Front

What is inertia?

Back

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

Front

What is the relationship between mass and acceleration in Newton's Second Law?

Back

As mass increases, acceleration decreases if the same force is applied.

Front

What is an example of Newton's Third Law in everyday life?

Back

When you jump off a small boat, you push the boat backward as you move forward.
