What is the name of Newton's First Law?

• Newton's Law of Force

What is inertia?

• an object's state in which the object stays at rest or keeps moving in the same direction until a greater force acts in the object

• an unbalanced force

• it is weight

What is a balanced force?

• Does not cause change in motion (Does not move)

• Causes change in motion (it moves)

• Causes a fast motion (moves really fast)

Newton's First Law of Motion says An object in______ with still in motion, and an object at rest will stay at ___________.

What is friction

• It is fire

• force equal in size and opposite in direction

• Two object rub together: friction slows down objects.

An example of Inertia is.....

• Gravity that is always acting on us

• Driver steps on the brakes, and your body continues moving (goes forward)

• Two sticks that causes fire
