The ballistic pendulum allows you to measure three easily found parameters: the mass of the projectile, the mass of the pendulum, and the height the pendulum rises after being struck by the projectile. From them, you can calculate a fourth, much less easily measured parameter -- the speed of the rapidly moving projectile.

Value of g by simple pendulum?
You can build a simple pendulum - one that has most of its mass concentrated in a small place, at the end of the pendulum. Measure the pendulum's length, and measure how long it takes to go back and forth. Use the formula for the period of a pendulum, solving for "g".
What happen to the time period if its lenght of the pendulum is changed?
If the length of a pendulum is increased, the pendulum will take longer to complete a swing, and the clock will slow down. Shortening the pendulum will speed up the clock.
Differences between compound pendulum and simple pendulum?
Compound pendulum is a physical pendulum whereas a simple pendulum is ideal pendulum. The difference is that in simple pendulum centre of mass and centre of oscillation are at the same distance.
Can friction decrease motion?
Yes. If you take a pendulum and set it swinging it's friction of the pendulum against the air, and internal friction in the line that will eventually slow the pendulum down.
What is special about pendulum swing?
No matter how high you set a pendulum, the amount of time for it to take one arc (maximum to maximum) will always remain the same.
Who was the first person to build a pendulum timekeeper?
Galileo Galilei

If pendulum is made to swing in water compare the time taken for this pendulum to come to a complete stop with the time taken by a pendulum swinging in air?
The pendulum will take more time in air to stop completely in comparision with water

What is a pendulum in science?
A pendulum is a piece of string attached to a 20 g mass that if you double the length it will take twice as long to swing.
What does a pendulum bob look like?
A bob is the weight on the end of a pendulum. It can take any shape, but is most often depicted as being round.
What is special about pendulum swing?

Why a compound pendulum is called equivalent simple pendulum?
Compound pendulum is a physical pendulum whereas a simple pendulum is ideal pendulum. The difference is that in simple pendulum centre of mass and centre of oscillation are at the same distance.
How do you make a rigid arm pendulum?
First you take a lond string and attach it to your arm then you get bouncy ball and add it to you Arm, now you have an Rigid Arm Pendulum.
How much time it take if the pendulum is relesed at angle 1.75 degrees instead of 3.5 degrees?
The period of the pendulum is unchanged by the angle of swing. See link.
