Who is Sir Issac Newton |
An english scientist and mathematician famous for his discovery of the Law of Gravity also discovered the three laws of motion. Published in his book Philosophiae Naturalis Principia Mathematica in 1687. |
|
|
Newtons First Law |
An object at rest tends to stay at rest and an object in motion tends to stay in motion unless acted upon by an unbalanced force. |
|
|
Newtons Second Law |
Forcw equals mass times acceleration. F=MA |
|
|
Newtons Third Law |
For every action there is an equal and opposite reaction. |
|
|
Inertia |
The tendency of an object to resist changes in its state of motion |
|
|
Acceleration |
A change in velocity. A measurement of how quickly an object is changing speed, direction or both. |
|
|
Velocity |
The rate of change of a position along a strait line with respect to time. |
|
|
Force |
Strength or energy |
|
|
Torque |
A turning or twisting force |
|
|
Momentum |
If an object is moving then it has momentum-it has its mass in motion |
|
|
Conservation of momentum |
If no exernal force acts on a system in a particular direction, then the total momentum of the system in the direction remains unchanged. |
