Motion and Forces Review

What is the net force on the block? (click on the words to view the picture)

• 5 Newtons up
• 5 Newtons down
• 15 Newtons up
• 15 Newtons down

which force produces a change in motion?

• unbalanced force
• balanced force
• gravitational force
• frictional force

What is a force that opposes motion between two surfaces?

• friction
• acceleration
• velocity
• motion

What is the difference between mass and weight?

• mass is how much matter is in an object, and weight is the gravitational pull on that object
• mass and weight are the same
• weight affects how much mass is in an object
• weight is determined by how many atoms make up an object

Which describes velocity?

• Speed with direction
• The same thing as speed
• how fast something is moving

Find the average speed of a train that traveled 540 km in 6 hours?

• 80 km/h
• 100 km/h
• 90 kn/h
• 3240 km/h

The picture of the position vs. time graph shows an object that is...

• accelerating/speeding up
• moving at a constant speed 
• not moving 
• accelerating/slowing down. 

If these boys are pulling with the same amount of force.  What will happen?

• The boy in blue will win.
• They will not move at all.
• The boy in red will win.
• Both will fall down.
