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.

Materials

* Scissors * Ruler * One (1) cardboard box approximately 12 inches x 12 inches x 18 inches * Duct Tape * Newspapers and weights to make the cardboard box weigh exactly 64 ounces (4 lbs.) * Four (4) eye hooks * Four (4) 3-ft.-long strands of nylon string * One (1) 4 ft. x 4 ft. piece of plywood or sturdy cardboard * Felt-tip marker * One (1) 4-ft. x 4-ft. sheet of white paper

What does it take to build a homemade pendulum?

To build a homemade pendulum, you will need a weight (such as a metal bolt or nut) attached to a string or wire. The weight should be suspended so it can swing freely. You can create a stand to hold the pendulum and mark positions for it to swing from to observe its movement. It's important to ensure the length of the string and the weight of the pendulum are consistent for accurate results.


What time does the pendulum take for one swing?

The time it takes for a pendulum to complete one full swing is determined by the length of the pendulum and the acceleration due to gravity. The formula for the period of a pendulum is T = 2π√(l/g), where T is the period, l is the length of the pendulum, and g is the acceleration due to gravity. Typically, a pendulum with a length of 1 meter will take about 2 seconds to complete one swing.


What energy conversions take place in a pendulum Why does the pendulum eventually stop?

In a pendulum, potential energy is converted to kinetic energy as it swings back and forth. Friction and air resistance gradually dissipate the kinetic energy, causing the pendulum to eventually stop swinging.


Does a pendulum get slower when it loses momentum?

Yes, a pendulum will slow down as it loses momentum due to the effects of friction and air resistance. This will cause the pendulum's swing to become shorter and take longer to complete.


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.

Who was the first person to build a pendulum timekeeper?

The first person to build a pendulum timekeeper was Dutch scientist and mathematician Christiaan Huygens in the 17th century. He developed the first accurate pendulum clock in 1656, which greatly improved timekeeping accuracy.

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 happen to the time period if its lenght of the pendulum is changed?

The time period of a pendulum is directly proportional to the square root of its length. If the length of the pendulum is increased, the time period will also increase. Conversely, if the length is decreased, the time period will decrease.


Who was the first person to build a pendulum that was a reliable timekeeper?

Galileo Galilei is often credited with building the first pendulum clock in the 17th century, but the first reliable pendulum clock is usually attributed to Dutch scientist Christiaan Huygens, who built one in 1656. Huygens' design greatly improved timekeeping accuracy and became the foundation for modern pendulum clocks.


How do you build foucault pendulum?

Any pendulum on a string ... free to swing in any direction ... can demonstratethe behavior associated with Foucault's pendulum. The only trick is that it has tokeep going for several hours before the behavior is obvious. So the task ofbuilding a Foucault pendulum is actually the task of building a pendulum thatdoesn't run down and stop. There are a number of simple electric/magnetic waysto do that, including the one I installed in 1968, to run the Foucault Pendulumin the lobby of the Oklahoma Science and Arts Foundation, at its old location atthe Oklahoma State Fairgrounds.
