Oscillatory Motion: Periodic Motion

The lesson covers two types of motion: transitional and periodic. Transitional motion involves a change in position relative to a fixed point, like a moving car. Periodic motion repeats at regular intervals, with examples including wave, oscillatory, and circular motion. Key concepts of oscillatory motion are discussed, such as amplitude, complete oscillation, periodic time, and frequency. The lesson concludes with a review of these main points.

Which type of motion involves a change in position relative to a fixed point?

• Periodic motion

• Transitional motion

• Circular motion

• Oscillatory motion

What is the term for the maximum displacement of an oscillating body from its original position?

• Frequency

• Periodic time

• Amplitude

• Complete oscillation

How is a complete oscillation defined?

• The number of oscillations per second

• The motion passing a fixed point twice in the same direction

• The maximum displacement from the original position

• The time taken for one oscillation

What does periodic time refer to in oscillatory motion?

• The motion passing a fixed point twice in the same direction

• The maximum displacement from the original position

• The time taken for one complete oscillation

• The number of oscillations per second

How is frequency defined in the context of oscillatory motion?

• The time taken for one complete oscillation

• The maximum displacement from the original position

• The number of complete oscillations in one second

• The motion passing a fixed point twice in the same direction
