Notes
... In this example, we dropped an object. While it was falling, its energy was constant...but changing forms. It only had gravitational potential energy, GPE, at beginning, because it had height but no velocity. Just before striking the ground (or in the example on the right, before hitting the hand) i ...

... relaxed level, yB = 0. Ball gets to a max height yC = 20.0 m above relaxed end of spring. (A) If no friction, find spring constant k. (B) Find speed of ball at point B. Ball starts from rest. Speeds up as spring pushes against it. As it leaves gun, gravity slows it down. System = ball, gun, Earth. C ...

Newton`s Laws of Motion - ISHR-G10
... The acceleration of an object is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. The two conclusions a α Fnet, and a α 1/m can be combined in one statement a is proportional to F/m or written as an ...
