Newton's 1st Law of Motion

What is Newton's First Law of Motion?

• F=m x a
• An object at rest stays at rest, an object in motion stays in motion unless acted on by another force. 

Which has more Inertia? (and more force to move) 

• Truck
• Ant

According to Newton’s first law of motion, a moving object that is not acted on by an unbalanced force will

• remain in motion.
• accelerate.

According to Newton’s first law of motion, an object at rest that is not acted on by an unbalanced force will

• remain in motion.
• remain at rest

Why does the penny fall in the cup?

• The penny is at rest so it stays at rest (gravity pulls it down)

• The penny is in motion
