3rd SW retest

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.

When you tell the direction and speed of an object, you give its

• motion
• velocity
• acceleration
• mass

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

Speed is equal to 

• Distance/Time
• Time/Distance
• Time x Distance
• Acceleration

Speed is different from velocity because

• Velocity has a direction
• Speed uses Distance /Time
• Velocity doesn't include time
• Velocity doesn't include distance

What is this graph showing?

• Constant Speed
• Acceleration (speeding up)
• Deceleration (slowing down)
• No motion

Calculate the Net Force. 

• 60N, Left 
• 40N, Right 
• 0N
• 60N, Right

Which example would be a balanced force?

• Train moving at a constant speed in the same direction.

• A skier going down a hill.

• A basketball being passed to a teammate.

• An apple falling to the floor.

The tendency of an object to resist changes in its motion is...

• inertia
• force
• acceleration
• velocity

Why is the net force 0 in the image?

• Because the elephants are the same size
• Because they are both pulling the same amount of force in opposite directions
• Because they are elephants
• Because they are pulling away from each other.
