When two equal and opposite forces are at work, what happens to motion?

• It increases
• It decreases.
• There is no motion.
• There is maximum friction.

What is the speed of a runner who runs 400 meters in 40 seconds? (speed = distance ÷ time)

• 10 meters/second
• 40 meters/second
• 100 meters/second
• 1,600 meters/second

When objects remain in the same place, it is called...

• gravity
• friction
• balanced force
• unbalanced force

Inertia is....

• for every action, there is an equal and opposite reaction
• larger objects take more force to move 
• an object in motion tends to stay in motion unless acted on by an opposite force
• a push that acts in the opposite direction and it slows down.
