Newton's Laws

Describe the motion of the car.

• The car has acceleration because it is at rest 
• The car does not have acceleration because it is at rest 
• The car has velocity because it is at rest 
• The car has acceleration because it is at rest 

In each of the following cases, determine where the car has no acceleration ?

• A car shortly after a stoplight turns green.
• A car approaching a red light
• A car with the cruise control set at 80 km/h
• A car turning a curve at a constant speed

What is a PUSH or PULL of an object?

• Motion
• Force
• Friction
• Gravity

Acceleration only takes place when things speed up. 

• True
• False

Acceleration of an object happens when things ________

• slow down
• go faster
• change direction (turn)
• All of the above

If you slow down on your bicycle, you accelerate.

• TRUE
• FALSE

A bowling ball with more mass requires which choice?

• more force to move the same speed as a less massive ball

• less force to move the same speed as a less massive ball

• the same force to move travel the same distance as a less massive ball

• less force to travel the same distance as a less massive ball

If the same force is applied to the bowling ball and baseball, which will accelerate faster and travel a further distance?

• the bowling ball

• the baseball

If the volleyball has the least mass and the basketball has the most mass, which ball would be closer to the starting line after the same amount of force is applied to all three balls?

• volleyball

• soccer ball

• basketball

If box A is 10kg and box B is 20kg which box would accelerate faster with the same amount of force applied to each box?

• box A

• box B
