Review Newton's Laws

The masses of four objects are given in this table. If all objects are struck with the same amount of force, which one will have the greatest acceleration?

• Object 1
• Object 2
• Object 3
• Object 4

Examine the table provided. Which of the objects is producing the greatest force?

• Soccer Ball
• Tennis Ball
• Marble
• Ping-Pong Ball

A person steps out of the boat and onto the dock.  As the person moves forward onto the dock, the boat moves backward.  Which statement best describes the backward motion of the boat as the person steps forward?

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

• Every mass exerts a force on every other mass.

• An object at rest tends to stay at rest.

• Friction opposes the motion of an object.

A semi truck and a Volkswagen (small car) traveling at the same speed have a head on collision. Which statement is correct?

• The impact force is greater on the Volkswagen.

• The impact force is greater on the semi truck.

• The impact force is less on the semi truck.

• The impact force is equal for both.

The image shows a game controller at rest. What best describes the action-reaction forces on the game controller?

• Action force = gravity. Reaction force = normal force of the table.

• Action force = gravity. Reaction force = friction between the controller and table.

• Action force = friction between the controller and table. Reaction force = gravity.

• Action force = normal force of the table. Reaction Force = gravity.

What is the resultant force?

• 40 N, Left

• 0 N, Balanced

• 400 N, Right

• 40 N, Right

A 20 kg bike accelerates at 10 m/s².  what was the force?

• 25 Newtons
• 20 Newtons
• 200 Newtons
• 10 Newtons

A force of 250 N is applied to an object that accelerates at a rate of 5 m/s².  What is the mass of the object? To solve this problem you must do - 

• 250 ÷ 5
• 5 ÷ 250
• 250 x 5
