What is velocity?
... What would happen if an unbalanced force acted on an object that’s already in motion? • It will change the speed or direction of the object. • Example: Your little brother is riding his tricycle. You run up behind him and give him a push. Your force adds to the existing force causing him to speed u ...

Lecture1_Inertia
... Notice that being at rest is just a special case of constant velocity (= zero). An object’s inertia will keep it from spontaneously changing its velocity: whether that’s starting to move from rest, or slowing down from a nonzero speed. It takes force to start something moving, but also to slow or st ...
