3rd Nine Week Benchmark Review

A balloon filled with air is released. The air in the balloon escapes and causes the balloon to move in the opposite direction. This is an example of

• Newton's 1st law

• Newton's 2nd law

• NEwton's 3rd law

Kelly and her friends are bowling. She uses an8kg bowling ball to bowl with in the first round. In the next round she uses a 10 kg bowling ball to bowl with. In order for Kelly to make the 10 kg ball accelerate at the same rate as the 8 kg bowling ball, what must she increase?

• force

• mass

• acceleration

• distance

When biking, Shawn finds that it requires more force to petal his bike when riding through grass than on concrete. This is mainly due to the force of

• friction

• gravity

• inertia

What two factors determine gravitational force?

• weight and distance

• mass and weight

• mass and distance

• size and time

The sun is much larger than the moon, but does not exert as much gravitational force on Earth. Why?

• The sun is a gaseous star, but the moon is solid.

• The sun is much closer to Earth.

• The moon is much closer to Earth.

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

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

A 45 kg student is seated in a desk. The student's force exerted on the desk is 45 kg. The desk exerts a 45 kg force on the student. This is an example of

• Newton's 1st law

• NEwton's 2nd law

• Newton's 3rd law

Soccer players are running toward a soccer ball that is currently stationary. The ball moves forward after being kicked by one of the soccer players. The ball stops after being caught by the soccer players at the goal. This is an example of

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

Force = mass x acceleration

• Newton's 1st law

• Newton's 2nd law

• Newton's 3rd law

Force is measured in

• newtons

• meters

• meters per second

• meters per second squared
