Question 1

Aristotle also correctly predicted that heavier objects fall faster than lighter objects.

Accepted Answer

FALSE

Question 2

A soccer ball resting on the grass will not move until

Accepted Answer

someone kicks it., an outside force is applied.

Question 3

Newton's first law is also known as

Accepted Answer

the law of inertia.

Question 4

Mass is the measure of the inertia of an object; weight is a measure of

Accepted Answer

Question 5

Before publishing his work, Newton had to first figure out

Accepted Answer

what mass & force was.

Question 6

What is the formula for weight?

Accepted Answer

W = mg

Question 7

Sir Isaac Newton published his work entitled "Principia" which built on Galileo's experiments.

Accepted Answer

TRUE

Question 8

What is "net force?"

Accepted Answer

the overall force acting on an object

Question 9

Galileo conducted experiments to study how objects behaved while moving.

Accepted Answer

TRUE

Question 10

Newton's second law is written mathematically as

Accepted Answer

F = ma, a = F/m

Question 11

Galileo also described his experiments by using mathematics.

Accepted Answer

FALSE

Question 12

Newton's first law of motion: an object in motion or at rest will not change - unless

Accepted Answer

an outside force acts on the object., the net force acting on the object is not zero.

Question 13

According to Newton's second law, if you double the force then the

Accepted Answer

acceleration will also double.

Question 14

Once the rolling soccer ball is kicked it will eventually slow down due (mostly) to

Accepted Answer

friction with the grass.

Question 15

Which statement best describes "mass?"

Accepted Answer

a measure of the inertia of an object

Question 16

Aristotle correctly described how an object moving at a constant speed needs a force to do so.

Accepted Answer

FALSE

Question 17

Which statement best describes "inertia?"

Accepted Answer

tendency of an object to resist change in motion

Question 18

If you double the mass in Newton's second law the object's acceleration will

Accepted Answer

will be cut in half.

Question 19

Newton's second law: the acceleration of an object is equal to the net force acting on it

Accepted Answer

divided by the object's mass.

Question 20

Which statement best describes "weight?"

Accepted Answer

the amount of gravity that is acting on an object
