What is the net force?

• 400 N Up

• 400 N Down

• - 400 N Down

• 800 N Down

How will this object move? 

• It won't move. 

• It will move to the left. 

• It will move to the right. 

• It will move in both directions. 

What is the net force?

• 40 N left

• 400 N right

• 0 N Balanced

• 40 N right

8 N to the left , and 4 N to the right. Find the net force. Is this balanced 

• 12 N Right  No

Friction is a force that acts in an ___________ direction of movement.

• similar

• opposite

• parallel

• west

Which type of friction occurs when objects are not moving?

• kinetic

• sliding

• static

• fluid

According to Newton's First Law of Motion, an object at rest will remain at rest unless acted upon by:

• An external force
  

• Its own inertia

• Friction

• Gravity

A force of 10 N is applied to a mass of 5 kg. What is the acceleration of the object?

• 1 m/s²
  

• 2 m/s²

• 5 m/s²

• 10 m/s²

Newton's Third Law of Motion states:

• The force of gravity acts downward
  

• An object in motion stays in motion

• Every action has an equal and opposite reaction

• Force is the product of mass and acceleration

A car traveling at a constant speed of 20 m/s suddenly stops due to hitting a wall. This is an example of:

• Balanced force

• Unbalanced force

• Frictional force

• Centripetal force
