Newton's Laws Of Motion Practice Test

The relationship between an object's mass (m), its acceleration (a), and the applied force (f) is F=MA. Acceleration and force are vectors. This Law requires that the direction of the acceleration vector is the same direction as the force vector.

Second Law

For every action there is an equal and opposite reaction.

Third Law

If you have a hockey puck sliding along a table, it will eventually come to a stop.

First Law

An object at rest tends to stay at rest and an object in motion tends to stay in motion in a straight line at a steady speed until an unbalanced force acts upon it.

First Law

Imagine a ball moving in a straight line directly toward when another ball collides with it. The moving ball exerts a force on the ball at rest. This causes the ball at rest to accelerate. However, the ball at rest also exerts the same magnitude of force (in the opposite direction) of the moving ball. This will cause the moving ball to accelerate or even move in another direction.

Third Law

Which law states the need to wear seat belts?

First Law

Who was the scientist that gave us the Laws of Motion?

Sir Issac Newton

What is another name for the Newton's first law of motion?

Law of Inertia

The blood in your head rushes to your feet when riding an elevator that is descending and abruptly stops.

First Law

If two people are pulling against each other with forces of 500N and 600N, there is a/an

unbalanced force

The tendency of matter to remain in constant motion unless acted on by an outside, unbalanced force is called...

Inertia

According to Newton's Third Law, action and reaction are...

equal and in opposite directions

If you push on a wall with a force of 10 Newtons, the force acting on you is?

10 Newtons

An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted upon by an unbalanced force

First Law

The acceleration of an object depends on the mass of the object and the amount of force applied

Second Law

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

Third Law

An object at motion will stay in motion FOREVER unless it is acted on by an _________ force. In many cases, that _________ force is ___________.

unbalanced; friction

_________ makes it harder to __________ an object with a large _______. It is also easier to move an object with a smaller _______.

Inertia; accelerate; mass

True or False:

In Newton's third law, the force exerted on you when you sit on a chair is more than the force exerted on you from the chair.

False

True or false:

a less massive object has more inertia than a more massive object.

False

A boy standing on a skateboard does not move until he pushes off.

First Law

A frog moves forward and the lily pad moves backward when the frog jumps from it.

Third Law

A girl is standing on a school bus. The bus suddenly moves forward and the girl falls backward.
