Frequency and Period in Motion

The video tutorial discusses uniform circular motion, focusing on the concepts of period and frequency. It explains that the period is the time taken to complete one cycle, while frequency is the number of cycles per second. The tutorial also connects these concepts to angular velocity, illustrating how period and frequency relate to the speed of rotation in radians per second. The video provides examples to clarify these relationships and introduces the formula for calculating period using angular velocity.

What is the notation typically used for period in the context of uniform circular motion?

• Lowercase f

• Capital F

• Capital T

• Lowercase omega

How is the period of a cycle defined in uniform circular motion?

• The time taken to complete half a cycle

• The time taken to complete a full cycle

• The speed of the object in motion

• The distance covered in one cycle

If a ball completes a cycle in 2 seconds, what is its period?

• 1 second

• 2 seconds

• 4 seconds

• 0.5 seconds

What is the relationship between frequency and period?

• Frequency is the square of the period

• Frequency is the reciprocal of the period

• Frequency is twice the period

• Frequency is half the period

What unit is commonly used to express frequency?

• Seconds

• Radians

• Hertz

• Meters

How do you calculate the period if you know the angular velocity?

• Divide 2π by angular velocity

• Multiply angular velocity by 2π

• Add angular velocity to 2π

• Subtract angular velocity from 2π

What is the formula to find frequency if the period is known?

• Frequency = 1 / Period

• Frequency = Period + 2π

• Frequency = Period × 2π

• Frequency = Period - 2π

In the example, if the angular velocity is π radians per second, what is the period?

• 1 second

• 2 seconds

• 2π seconds

• π seconds

If the period is 2 seconds, what is the frequency?

• 4 Hz

• 0.5 Hz

• 1 Hz

• 2 Hz

What does a frequency of 0.5 Hz indicate about the cycles completed per second?

• 4 cycles per second

• 0.5 cycles per second

• 1 cycle per second

• 2 cycles per second
