• left

• it will not move

Multiple Choice

This image shows an example of which of Newton’s laws?

• The force of an object is the product of its mass multiplied by its acceleration

• A force of attraction exists between any two objects with mass

• For every action, there is an equal and opposite reaction

Multiple Choice

A skateboarder runs for a few steps and then jumps on his skateboard. His initial applied energy carries him across a level surface for about 30 seconds. The skater notices that he has skated a long time without ever having to push off the ground again. Which of Newton's law does this describe?

• Newton's 1st law- inertia (objects in motion stay in motion, objects at rest stay at rest)

• Newton's 2nd law- force equals mass x acceleration

• Newton's 3rd law- for every action there is an equal and opposite reaction
