law
force
Newton
change
Why won't objects in motion continue moving forever?
Because of forces such as friction, air resistance and gravity
An object can continue to move on forever
Because of speed and acceleration
What is Newton’s third law of motion?
For every action there is an equal and opposite reaction.
For a heavy object you need a greater force
An object won't change its motion unless a force acts upon it
