Newton's laws

What law is best described by inertia?

• 1st law of motion

• 2nd law of motion

• 3rd law of motion

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

• remain in motion.
• eventually come to a stop.
• change its momentum.
• accelerate.

A person in car  slides to the right when going through a very sharp left turn on the highway. 

• 1st Law
• 2nd Law
• 3rd Law

What is Newton's 2nd Law?

• For every action there is an equal and opposite reaction.

• Acceleration depends on two variables, the mass of the object and the amount of force.
