Chapter 6 - Newton's Third Law - Review!

Front

What is Newton's 1st Law of Motion?

Back

An object at rest tends to stay at rest and an object in motion tends to stay in motion unless acted on by an outside force (inertia).

Front

What is Newton's 2nd Law of Motion?

Back

Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (F = ma).

Front

What is Newton's 3rd Law of Motion?

Back

Whenever one object exerts a force on another object, the second object exerts an equal and opposite force on the first object.

Front

Define inertia.

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

If a 10 kg object is acted upon by a force of 50 N, what is its acceleration? (a = F/m)

Back

5 m/s².

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What happens to the acceleration of an object if the mass is doubled while the force remains constant?

Back

The acceleration is halved.

Front

In a collision, if object A exerts a force on object B, what can be said about the force exerted by object B on object A?

Back

Object B exerts an equal and opposite force on object A.

Front

What is the relationship between mass and acceleration in Newton's 2nd Law?

Back

Mass and acceleration are inversely related when force is constant.

Front

If a car accelerates at 3 m/s² and has a mass of 1200 kg, what is the force applied? (F = ma)

Back

3600 N.
