Mass
|
Quantity of matter in object
Measure of inertia of object Measured in kilograms (kg) Measured with a balance |
|
|
Weight
|
Measure of force of gravity on an object
Measured in newtons (n) Measured with a spring scale Changes based on location where its measured. |
|
|
Inertia
|
Resistance to a change in state of motion
A PROPERTY of matter Amount of inertia based on mass only. |

|
|
Gravity
|
Force that exists between Earth and objects that are near it

|
Universal Gravitation
|
Force of attraction between all objects in the universe
|
|
|
Acceleration due to Gravity
|
Acceleration experienced by object when the only force acting on it is gravity
9.8 m/s/s on Earth |
|
|
Law of Universal Gravitation
|
Proposed by Sir Isaac Newton
All objects in universe attract all other objects with a force that is directly proportional to mass and inversely proportional to distance between objects. |
|
|
Newton's First Law of Motion
|
Objects at rest remain at rest and objects in motion remain in motion unless acted on by an unbalanced force.
Also known as "Law of Inertia" |
