Question 1

1.

What does Newton's second law of motion tell us?

Weight equals mass times acceleration

Force equals mass times acceleration

Energy cannot be created nor destroyed

Question 2

2.

According to Newton's second law, if the force applied on an object is increased, the acceleration will also increase assuming the mass remains constant.

True

7.

What happens to an object when you apply a force to it, according to Newton's second law?

It moves

It accelerates

It changes shape

It changes weight

Question 8

8.

In Newton's second law, the direction of the acceleration is given by the direction of the net force.

0 m/s^2

9.8 m/s^2

Depends on the object's mass

Depends on the object's weight

Question 10

10.

What happens when more force is applied to an object of constant mass, according to Newton's second law?

It accelerates faster

It changes direction

It decelerates

It stops

Question 11

11.

In the absence of an external force, an object at rest will remain at rest according to Newton's Second Law.

True

False

Question 12

12.

If you double the mass of an object, what happens to the acceleration assuming the force stays the same?

It doubles

It halves

It stays the same

It quadruples

Question 13

13.

According to the second law, when the same amount of force is applied to two objects of different masses...

The heavier object will have greater acceleration

Both will have the same acceleration

Neither will accelerate

Question 14

14.

Newton's second law of motion is also known as the law of momentum.

True

False

Question 15

15.

The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, inversely proportional to the mass of the object, and is in the same direction as the net force. This definition refers to ...
