Ball 1 Has uchanging motion because it continually goes up no matter what. Ball 2 has no motion. And ball 3 changing motion because it goes from not moving to moving. Hope this helps
The equation used to calculate the weight of an object on a plant is F = ma. "F" is the force measures in Newtons, "m" is the mass measures in grams and "a" is the acceleration that accur due to gravity.
Explanation:
the velocity graph of a ball mass 20mg moving along a straight line
Let the vector position of the object in the (x-y) plane be

The applied force is

By definition, the applied torque is
