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

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 ss

• 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

The pendulum is said to have completed one ............ when its Bob starting from the mean position, moves to the extreme positions and comes back to the mean position.

In class we used this pendulum simulation to determine the relationship between the length of the pendulum and the frequency of the pendulum.

In our experiment, we changed the length of the pendulum (dependent variable) and we measured the time it took for the pendulum to swing or return to start 10 times (dependent variable).

When we looked at our data, we noticed that when we increased the length of the pendulum, the time it took to swing also increased. This means that the frequency of the pendulum decreased.

We can conclude that if we increase the length of the pendulum, the frequency will decrease. In other words, the longer the pendulum is, the slower it moves.

• I don't get it.

• GOT IT!

In an experiment it is important to only change the dependent variable. What variables did we keep the same? CHOOSE THREE

• The mass of the pendulum

• The angle of the drop

• The amount of friction

• The length of the pendulum
