A body continues in a state of rest or uniform velocity unless acted upon by an external force
1 of 10
Newton’s second law of motion
The rate of change in momentum experienced by an object is directly proportional to the size of force applied and takes place in the same direction as the force applied
2 of 10
Linear motion
When a body moves in a straight or curved line, with all parts moving the same
3 of 10
Angular motion
When a body moves in a circular path about an axis of rotation
4 of 10
Effects of force
Motion, acceleration, deceleration, change of direction or shape of a moving object
5 of 10
Size of force
The greater this is when applied to an object the greater the change in momentum
6 of 10
Centre of Mass
The point at which the body is balanced in all directions
7 of 10
Stability
The degree to which body is balanced, steady and difficult to move
8 of 10
Newton’s third law of motion
For every action force there is an equal and opposite reaction force
9 of 10
General motion
A combination of linear and angular motion
