Oscillatory motion - simple pendulum

In the opposite figure, a body moves in an oscillatory motion, so the distance which is moved by the body during a complete oscillation equals .......................

• double the distance ab

• double the distance bc

• half the distance ac

• four times the distance bc

In the opposite figure the pendulum makes a complete oscillation when ......................

• it moves from x to z two times

• it moves from x to y four times

• it passes through point x two successive times in the same direction

• it passes through point y three times in the same direction

The ratio between the time of an amplitude and the time of a complete oscillation is ......................

• 2/1

• 1/2

• 4/1

• 1/4

The opposite figure shows the motion of a vibrating string which has a periodic time T, so the time taken by the string to reach the maximum displacement from its equilibrium position is ........................

• T/4

• T/2

• T/1

• 2T

The opposite figure shows a simple pendulum, if its bob has moved from position x to position y then to position z, the magnitude of the displacement of the pendulum bob equals .............................

• A

• 2A

• 3A

• 4A

If a vibrating object makes 90 oscillations in one minute, then its frequency equals ........................................

• 90

• 60

• 1.5
