An object experiences a net zero external unbalanced force is it possible for the object to be travelling with a non zero velocity. if yes state the condition that must be placed on the magnitude and direction of the velocity. if no, provide a reason . |
|
Answer» net zero external unbalanced FORCE is applied on the body, it is possible for the OBJECT to be travelling with non-zero velocity.In fact , once an object comes into motion & there is a condition in which is imposed by any external force; the object will CONTINUE to remain in motion. It is necessary that the object moves at a CONSTANT velocity & in a particular direction. |
