|
Newton's First law |
A force is necessary to change the state of rest or uniform motion in a straight line of a body. |
|
|
Linear Momentum |
The mass of an object multiplied by its velocity. It is a vector. |
|
|
Newton's second law |
The rate of change of the momentum of an object is directly proportional to the net force acting on it. |
|
|
Newton's third law |
When body A exerts a force on body B, then body B exerts on body A a force that is equal,opposite in direction and of the same type. |
|
|
Impulse |
A quantity which is equal to the change in momentum of a body. |
|
|
Perfectly elastic collision |
A collision in which no momentum or kinetic energy is lost. |
|
|
Inelastic collision |
A collision in which momentum is conserved, but kinetic energy is not. |
|
|
One Radian |
The angle subtended at the centre of a circle by an arc of length equal to the circle's radius. |
|
|
Period |
The time it takes in circular motion for a object to complete one revolution. |
|
|
Centripetal acceleration |
The acceleration of an object travelling in a circle acting towards the centre of the circle. |
|
|
Field |
A region in which a force operates. |
