Q

Tendancy of a body to maintain it’s state of rest or motion

A

Inertia

17
Q

The force of gravity on an object

A

Weight

18
Q

Property of an object that specify how much resistance an object exhibits to change

A

Mass

19
Q

Enumerate Newton’s Law of Motion

A
  1. An object at rest will remain at rest unless acted upon by a net force and an object in motion will remain in motion unless acted upon by a net force
  2. Force is equal to mass multiplied by acceleration
  3. For every action, there is an equal and opposite reaction.
20
Q

This refers to the motion of objects in an inertial reference frame

A

Newton’s Law

21
Q

What is the difference between weight and mass? Elaborate your answer

A

Mass is unchanging, your mass is equal here on earth as so in the vacuum of space or in the surface of the moon

But weight depends on gravity, your weight is different in the surface of the moon, compared here on earth

22
Q

What is one way to calculate the mass of an object?

A

By mutiplying the volume and density of an object, you’ll get the mass :>

Mass = volume x density
