2.) Newton's First Law of Motion states:

• An object in motion stays in motion unless a force acts on them
• An object's acceleration (change in speed) depends on the mass of the object and the amount of force applied on it
• An object at rest stays at rest unless a force acts on it
• Every action has an equal and opposite reaction
• An object in motion stays in motion, an object at rest stays at rest unless a force acts on them

3.) Newton's Third Law of Motion states:

• Objects in motion stay in motion forever unless a force acts on them
• An object's acceleration (change in speed) depends on the mass of the object and the amount of force applied on it
• An object at rest stays at rest unless a force acts on it
• Every action has an equal and opposite reaction
• Objects in motion stay in motion, objects at rest stay at rest forever unless a force acts upon them.
