Newton's Laws

Question 1

What is Newton’s 1st Law also known as?

Answer 1

Law of Inertia

Question 2

What is Inertia?

Answer 2

Ability of an object to resist a change in its state of motion; an object wanting to stay where it is

Question 3

What is Newton’s 2nd Law of Motion?

Answer 3

The change of motion is proportional to applied force, and is in the direction which that force acts; ΣF=ma (units=N)

Question 4

If a mass had an unbalanced force acting upon it, which way the acceleration produced?

Answer 4

In the same direction of the force

Question 5

What is the force equation for a mass in equilibrium?

Answer 5

ΣF=0

Question 6

What is Newton’s 3rd Law of Motion?

Answer 6

For every action, there is an equal and opposite reaction

Question 7

Forces occur in _________.

Answer 7

Pairs (mutual interaction)

Question 8

If a hand pushes against a wall at 2N, is the wall pushing back?

Answer 8

Yes, according to Newton’s 3rd Law, the wall pushes back with 2N

Question 9

What is Newton’s 1st Law of Motion?

Answer 9

Every body continues in its state of rest, or of uniform motion in a straight line, unless it is compelled to change that state by forces acting on it
