... The medium exerts a resistive force, R , on an object moving through the medium The magnitude of R depends on the medium The direction of R is opposite the direction of motion of the object relative to the medium R nearly always increases with increasing speed ...

... compressed or stretched spring upon any object which is attached to it. An object which compresses or stretches a spring is always acted upon by a force which restores the object to its original position. The fun you have on a trampoline or pogo stick or the soft ride on a bike with shock absorbers ...

... Acceleration • A body experiences acceleration when there is a change in its state of motion: – Can either be an increase or a decrease in velocity! – Change in velocity = change in speed, direction, or both. ...

The Coriolis Force
... For example, suppose we’re on the surface of the Earth, in the northern hemisphere, and hit a golf ball due south with velocity v. Since the Earth rotates to the east, the Earth’s angular velocity vector is along the Earth’s axis, northward out of the north pole. Then by Eq. (8), there will be a w ...
