Which of the images below show Newton's 3rd Law of Motion?

F = MA can help us take Newton's 3rd Law another step further in understanding motion!!

This video connects physics to car crashes!

Multiple Choice

What is an opposing force?

• A force in the same direction with same strength.

• A force in an opposite direction with same strength.

Multiple Choice

For every action there is an equal and opposite reaction.

• Newton's First Law of Motion

• Newton's Second Law of Motion

• Newton's Third Law of Motion

Multiple Choice

When a car collides (action) into a fire hydrant, they both move (reaction). Is this considered a force pair?

• Yes

• No

Multiple Choice

If you push on a wall with a force of 30 N, the force acting on you from the wall is which of the following?

• 0 N

• 10 N

• 20 N

• 30 N

Multiple Choice

Based on Newton's third law of motion, when a person on a skateboard throws a heavy concrete block to the north, the person will be pushed to the ___________.

• north

• south

• east

• west

Multiple Choice

Which law explains how rockets are launched into space?

• Newton's First Law of Motion
• Newton's Second Law of Motion
• Newton's Third Law of Motion
• Newton's Fourth Law of Motion

Multiple Choice

How many Laws of Motion are there?

• 1
• 2
• 3
• 4

Multiple Choice

Which best explains why we are able to accelerate forward when starting to run?

• As one leg moves backward, it provides an equal and opposite force for the other foot to move forward.
• No acceleration takes place. Runners are always at a fixed velocity.
• The striking foot pushes backward against the ground. The friction with the ground provides an equal and opposite force forward.
• The runner's upper body quickly leans forward, causing the entire body to begin accelerating forward

Multiple Choice

What happens when two objects, such as a baseball and a bat, collide?

• They hit each other with the same force in the same direction.

• They hit each other with the same force in opposite directions.

• They hit each other with unequal force in opposite directions.

• One remains still while the other one moves in the same direction.

Multiple Choice

By pushing backwards a roller skater moves forward. This is an example of Newton's

• First Law

• Second Law

• Third Law

• Law of Gravity

Multiple Choice

The resistance of an object to any change in its motion is called ______________________.

• inertia

• friction

• gravity

• weight
