|
A force is necessary to change the state of rest or of uniform motion in a straight line of a body.

|
Newton's Second Law
|
The rate of change of the momentum of an object is directly proportional to the resultant net force acting upon it.
|
|
|
Linear Momentum
|
this is defined by the mass of an object multiplied by its velocity. It is a vector.
|
|
|
Impulse
|
Impulse is defined by the expression F*change in time. It is equal to the change in momentum. It also equals the area beneath a force-time graph.
Note: The force of an impact can be reduced by increasing the time of the impact. |
