... Previously we assumed that the body moved from P1 to P2 with constant speed. If the linear speed of the body changes then, obviously, the angular speed (velocity) also changes. The angular acceleration, α, is the rate of change of angular velocity. So, if the angular velocity changes uniformly from ...

2. Laws of Motion
... If the resultant force acting on an object is not zero, all the forces are said to be unbalanced. This forms the basis of Newton’s second law of motion, which states: If the forces on an object are unbalanced, two things about the object can change: the speed of the object may change – it may eith ...
