Laws of Motion ?
|
3 Laws formulated by Sir Isaac Newton, an English Scientist
|
|
|
The Laws of Motion were based on what?
|
Based on the study of how and why things move
|
|
|
What is the first law of motion?
|
An object at rest will remain at rest. An object in motion will continue moving in a straight line at a constant speed until an outside force acts on it.
|
|
|
Inertia?
|
an objects ability to resist a change in motion
|
|
|
An object's acceleration depends on the size of the force acting on it and on the mass of the object
|
Second Law of Motion
|
|
|
Second Law of Motion is affected by____? (3 things)
|
1) the mass of the object
2) the size of the force 3) the direction of the force |
|
|
Third Law of Motion
|
for every action there is an equal and opposite reaction.
1st is the action the force pushes or pull back and that is reaction force. |
