Question 1

Newtons First Law?

Answer 1

An object at rest will remain at rest or an object in motion remains in motion
ΣF =0 (No acceleration)

Question 2

Newtons Second Law

Answer 2

A force on a body is equal to its mass times acceleration
ΣF=ma

Question 3

Newtons Third Law

Answer 3

For every action, there is an equal and opposite reaction

Question 4

inertia is the same as?

Answer 4

Mass

Question 5

Scaler vs Vector

Answer 5

Scaler = quantity described by magnitude only example Mass, time temperature, length
Vector = Quantity described by Magnitude and Direction
example: acceleration, velocity force, displacement
