Acceleration and Force

What is a measure of the change of velocity of a moving object?

• speed
• acceleration
• motion 
• velocity 

If the velocity vector and acceleration vectors are moving in the same direction then

• speed will increase.
• speed will decrease.
• speed will be constant. 

Which is not an example of acceleration?

• Driving at a constant speed 
• A bat hitting a ball
• Throwing a football 
• Kicking a soccer ball
