Forces #5 (Review)

What is the formula to calculate velocity?

If a car accelerates from 0 m/s to 20 m/s in 5 seconds, what is its acceleration?

Newton's First Law of Motion is also known as:

• Law of Acceleration

• Law of Inertia

• Law of Action-Reaction

• Law of Gravity

According to Newton's Second Law of Motion, force is equal to:

Newton's Third Law of Motion states:

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

• An object in motion stays in motion.

• Force equals mass times acceleration.

• Objects fall at the same rate regardless of mass.

A car travels south 200 meters in 2 hours. What is its average velocity of the car?

• 200 m/s

• 100 m/s

• 0.5 m/s

• 2 m/s

What is the net force on an object if two forces, 300 N to the right and 400 N to the left, are acting on it?

• 300 N to the right

• 700 N to the left

• 400 N to the left

• 100 N to the left

• 30 N

• 3 N

• 10 N

• 300 N

What is the net force acting on the object?

• 75 N Right

• 125 N Left

• 50 N Right

• 50 N left

An object remains at rest/motion unless acted upon by an external force. This statement is:

• Newton's First Law

• Newton's Second Law

• Newton's Third Law

• Newton's Law of Universal Gravitation
