SIMPLE PENDULUM CLASS 7

The to and fro motion of a simple pendulum is an example of a periodic or an .............. motion.

• Rectilinear

• Oscillatory

• Circular

• Rotational

A simple pendulum consists of a small metallic ball or a piece of stone suspended from a rigid stand by a thread. The metallic ball is called the ........... of the pendulum.

• Oscillation

• Extreme position

• Bob

• Thread

The time taken by the pendulum to complete one oscillation is called its .......... .

• Time period

• Time speed

• Distance covered

• Total time

The time taken by a simple pendulum to complete each oscillation remains ......... .

• Different

• Same

• Both (a) and (b)

• None of the above

The formula to find the total time taken by a simple pendulum is:

• Total Time Taken= Speed × Distance

• Total Time Taken= Time period/ No. of Oscillations

• Total Time Taken= Time period × Number of oscillations

A simple pendulum takes 30s to complete 18 oscillations. What is the time period of the pendulum?

• 166.0 s

• 0.166 s

• 16.6 s

• 1.66 s

The time period of a simple pendulum is 1.6 s. Find the total time taken by it in 28 oscillations.

• 448 s

• 44.8 s

• 4.48 s

• 0.448 s

If we denote speed by S, distance by D and time by T, the relationship between these quantities is

• S= D×T

• S= T/D

• S= D/T

The instrument in a car is used for measuring the distance travelled by car is

• Odometer

• Speedometer

• Barometer

• Anemometer
