... Every object continues either at rest or in constant motion in a straight line, unless it is forced to change that state by forces action on it. An object acted on by no net force moves with constant velocity (which may be zero) and thus with zero acceleration. Zero resultant force is equivalent to ...

... not because there is an external force acting on the ball to pull it inward. The moment of inertia and angular speed will, of course, remain the same throughout the process because the ball is rotating in the same plane throughout the motion. 13. •A freely rotating turntable moves at a steady angula ...

Conservation of Angular Momentum
... The torque produced by the external force f ext about some reference point is equal to product of the perpendicular moment arm "d" and the force, i.e. T d f ext . Or, in vector form, the torque is the cross product position vector r from the reference point and f ext , i.e. T r f ext . These ...

Motion and Forces Study Guide
... First law of motion (law of inertia) An object at rest will remain at rest and an object in motion will remain in motion at constant velocity unless acted upon by an unbalanced force. Inertia is the property of matter that tends to resist any change in motion. The more massive an object is, the ...
