_______________ is how fast an object changes over time. 

• speed

What is the formula for force?

• F=M/A
• F=A/M
• F=M*A
• F=M*F

What effect does friction have on a moving object?

• it causes the moving object to slow and eventually stop

• it causes the moving object to speed up

• it keeps the moving object moving in the same direction forever

• it causes the moving object to turn around and move in the opposite direction
