A car is moving with constant motion (in a straight line at the same speed). What type of force would cause the car's motion to change?

• Balanced force

• Unbalanced force

Ted is trying to move a fridge through his house, he gets stuck on a carpet and even though he is pushing the fridge, it is not moving. What force is acting against him?

• gravity
• friction
• air
• mass

A push or pull exerted on an object

• Force
• Net force
• Momentum
• Speed

How does friction affect speed?

• more friction decreases speed
• more friction increases speed
• less friction decreases speed

What is the net force

• 10 N
• 0 N
• 25 N
• 1 N

What is the net force?

• 40 N left
• 0 N Balalnced
• 400 N right
• 40 N right

Forces that have a net force that is not zero.

• Balanced force
• Unbalanced force

What is the net force?

• 400 N Up
• 400 N Down
• - 400 N Down
• 800 N Down

Which way is the object moving?

• It is not or moving at a constant speed
• moving to the right
• moving to the left
• going up

Which is moving at a constant speed or not at all?

• a
• b
• c
• d
