What is a pendulum?

Back

A pendulum is a weight (bob) attached to a string or rod that swings back and forth under the influence of gravity.

Front

What is the bob of a pendulum?

Back

The bob is the mass or weight at the end of the pendulum that swings.

Front

At which point in the swing of a pendulum is the bob moving fastest?

Back

At the bottom of the arc.

Front

What factors affect the period of a pendulum?

Back

The length of the pendulum and the acceleration due to gravity affect the period; mass does not.

Front

What happens to the period of a pendulum as its length increases?

Back

The period increases.

Front

What is the period of a pendulum?

Back

The time it takes to complete one full cycle (one complete to and fro motion).

Front

What is the relationship between the length of a pendulum and its period?

Back

Longer pendulums have longer periods; they take more time to swing back and forth.

Front

What is the formula for the period of a simple pendulum?

Back

T = 2π√(L/g), where T is the period, L is the length, and g is the acceleration due to gravity.

Front

What is the effect of gravity on a pendulum's period?

Back

Increased gravity results in a shorter period; the pendulum swings faster.

Front

What is meant by 'one complete cycle' in the context of a pendulum?

Back

One complete cycle is the motion from the starting point to the opposite point and back.
