Applying Newton's Laws

A soccer ball is sitting in the middle of a field. The ball will remain at rest until an outside force like a players foot or the wind acts upon it. Which of Newton's laws is represented by this?

• 1st

• 2nd

• 3rd

Think about pushing a shopping cart and a car. If you apply the same amount of force to both, the shopping cart will travel fast, but the car will hardly move. To move the car yo would need a larger force. Which of Newton's laws is being represented?

• 1st

• 2nd

• 3rd

Sally jumps on her trampoline. She exerts a force on the trampoline and the trampoline exerts an equal but opposite force back on Sally. This represents

• Law 1

• Law 3

• Law 2

What Newtons law does this picture represent

• Newtons 1st law

• Newtons 2nd law

• Newtons 3rd law

• Newtons 4th law

Which law explains that it would take more force to push the car than the lawnmower?

• 1st

• 2nd

• 3rd

When you are running. your foot exerts force on the ground and the ground exerts force back onto you. Which of Newton's laws is represented

• 1st

• 2nd

• 3rd

If we put the same force on a bowling ball and a soccer ball, the soccer ball will move faster! Which law explains this?

• 1st

• 2nd

• 3rd

Which way would a swimmer push to move forward in the water?

• To the left

• Forward

• Backward

The reason a ball bounces up when it hits the ground:

• The ball and ground repel each other.

• The ball exerts a force on the ground, and the ground exerts a force on the ball.

Watch as Blake pushes the 2 cars of different masses with about the same force. Observe what happens. Which of Newton's Laws does this represent?

• Newton's 1st Law, inertia

• Newton's 2nd Law, Force = m x a

• Newton's 3rd Law, action/reaction

Answer explanation

Newton's 2nd Law is the relationship between force, mass and acceleration. The car with less mass travels further when pushed with the same force as the car with more mass.
