Science Review

An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

• Newton's First Law

• Newton's Second Law

• Newton's Third Law

What is Newton's Second Law?

• Law of Interia

• Force = Mass x Acceleration

• Action - Reaction

• Net Force

What is inertia?

Newton's third law states?

• F = M * A Force = Mass x Acceleration

• An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

• Inertia is the tendency to resist motion.

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

How is speed different from velocity?

• Speed has a direction.

• Velocity needs a direction.

• Velocity is greater than speed.

What is acceleration?

• Change in velocity

• Change in direction

• Change in velocity and direction
