... Example: A Satellite’s Motion A satellite moves at constant speed in a circular orbit about the center of the Earth and near the surface of the Earth. If the magnitude of its acceleration is g = 9.81 m/s2 and the Earth’s radius is 6,370 km, find: (a) its speed v; and (b) the time T required for one ...

Chapter 13: Periodic Motion
... • In real world dissipative forces such as friction between a block and a table exist. Such a dissipative force will decrease the amplitude of an oscillation – damped oscillation. The friction reduces the mechanical energy of the system as time passes, and the motion is said to be damped. ...

Force and Motion
... If there is a non-zero (unbalanced) force applied to an object, it will accelerate. The acceleration is proportional to the force but is different for every object. The proportionality constant is “m” and is called the mass. The mass of an object is a measure of the total “amount of matter” containe ...

Forces and Motion
... An object in motion will stay in motion and an object at rest will stay at rest until acted on by a force. Basically stated… objects keep moving until something slows them down (friction) and objects will stay still until something causes them to move (force) ...

... the gravity force pulling the mass down the ramp? As you slowly put the mass on the ramp, the ramp compresses & stretches along the ramp as gravity tries to slide the mass down the ramp. When you let go, the ramp has stretched enough to push on the mass with EXACTLY the right amount of force up the ...
