Circular Motion

Circular Motion. Circular motion equations:. v = 2 ? r f. Example 1 : A 2 kg body is tied to the end of a cord and whirled in a horizontal circle of radius 2 m. If the body makes three complete revolutions every second, determine its period and linear speed. m = 2 kg r = 2 m

For a central force the position and the force are anti-parallel, so r ?F = 0.

For a central force the position and the force are anti-parallel, so r ?F = 0. r. F. N is torque. Newton II, angular. So, angular momentum, L, is constant. Since the Angular Momentum, L , is constant:. Its magnitude is fixed Its direction is fixed. L. r. p.

What similar action is involved in all of the following activities?

What similar action is involved in all of the following activities?. You pedal a bicycle to start moving then apply the brakes to make it stop moving. You hit the accelerator (gas pedal) to make a car speed up after the light turns green, then you hit the brakes to stop for the next red light.
