What is Newton's Third Law?

• Object in motion stays in motion and an object at rest stays at rest unless acted on by a outside force
• Force = mass x acceleration
• For every action there is an equal and opposite reaction

According to Newton's second law, if you increase the force applied to an object :

• it accelerates more
• it doesn't move
• you get more inertia
• it decelerates

Newton's first law of motion states that __________.

• when a force is applied on an object, there is an equal force applied by the object in the opposite direction
• hen a force acts on an object, its acceleration is in the same direction as the force
• an object will remain at rest or keep moving with a constant velocity unless a force acts on it
• cceleration is calculated by dividing the force exerted on an object by the mass of the object

What kind(s) of objects have inertia?

• all objects with mass
• only objects at rest
• only objects in motion
• only objects whose motion is being changed
