Unit 4 Lesson 15 Identifying Action-Reaction Force Pairs Quiz

When a cannon fires a cannonball there is an interaction between the two objects, so there are action and reaction forces. The cannon recoils only slightly as it shoots out the cannonball, but the cannonball goes flying through the air. Why is the acceleration greater on the cannonball?

• There are multiple forces being exerted on that object

• The force is greater on that object because its mass is greater

• The action force on the cannonball is greater

• The effect is greater on that object because its mass is smaller

• The reaction force on the cannon is less

What is Newton's third law of motion?

• Each action force has an opposed and equal reaction force

• Acceleration is directly proportional to mass and inversely proportional to force

• Action equals reaction

• Acceleration is directly proportional to force and inversely proportional to mass

• Each reaction force has an opposed and equal action force

What does it mean to say that 'action always equals reaction'?

• Reaction force will always be 600 N

• The two objects have to be the same size to have the same magnitude force

• The magnitude of the reaction force is dictated by the action force that begins the interaction

• The action force will be the same direction as the reaction force

• The action force can only be as large as the reaction force

What does it mean to say that mass and acceleration are inversely proportional?

• As mass increases so does the action force

• As one gets smaller, so does the other

• As one gets larger, so does the other

• As one gets larger the other gets smaller

• As mass decreases the action force increases

Which statement is NOT true about action and reaction forces?

• Action always equals reaction
