Forces

What is defined as a push or pull

• force
• motion
• vector
• speed

How will this object move? 

• It won't move. 
• It will move to the right. 
• It will move to the left. 
• It will move in both directions. 

The tendency to resist a change in motion is called

• Net Force
• Gravity
• Inertia
• Balanced Forces

Newton's 2nd Law of Motion gives us the formula, ____

• F = mv
• F = ma
• F = dt
• F = vt

How does friction affect speed?

• more friction decreases speed
• more friction increases speed
• less friction decreases speed
• less friction doesn't affect speed

Which would NOT be a way of reducing friction?

• making the surfaces smoother
• using lubricants such as waxes, oils, or grease
• changing from sliding friction to rolling friction using ball bearings
• Using kitty litter on snow and ice to help your car gain traction

Unbalanced forces result in _________

• constant velocity
• inertia
• gravity
• acceleration
