# Is A Ballistic Pendulum Elastic Or Inelastic?

## How do you find the momentum of a pendulum?

1.

From momentum conservation, the speed V of the ball and pendulum just after they collide is given by: ● V = mu/(M+m) ● where u = X * sqrt (g/2Y)..

## What type of collision is studied in ballistic pendulum experiment?

Ballistic Pendulum – An Inelastic Collision Something as simple as a wooden block can be used to measure the muzzle velocity of a bullet. Known as ballistic pendulums, these devices have been used for decades in labs and classrooms to help investigate the conservation of energy and momentum.

## Which ball is more elastic?

rubber ballWhen all three balls are dropped from the same height, the rubber ball will bounce the highest because it has the greatest elasticity. When the rubber ball hits the ground it gets compressed, or squished, and because it is very elastic, it quickly returns to its original shape.

## Why are bouncy balls Bouncy?

The ball can bounce because of the cross-linked polymers. Since the long polymer chains are flexible, when the ball hits the ground, it is able to momentarily deform or squish. The polymers also make the ball elastic meaning it tends to retain its shape.

## Is linear momentum conserved in a pendulum?

The system can also dissipate kinetic energy in producing sound or heat. Since there are no external forces acting on the system at the time of the collision, linear momentum must be conserved in both cases. … A ratchet and pawl system catches the pendulum at the height of its swing.

## Why is a car crash inelastic?

An inelastic collisions occurs when two objects collide and do not bounce away from each other. Momentum is conserved, because the total momentum of both objects before and after the collision is the same. However, kinetic energy is not conserved. … A high speed car collision is an inelastic collision.

## What happens during inelastic collision?

An inelastic collision is a collision in which there is a loss of kinetic energy. While momentum of the system is conserved in an inelastic collision, kinetic energy is not. … Thermal energy, sound energy, and material deformation are likely culprits.

## What is a totally inelastic collision?

A perfectly inelastic collision—also known as a completely inelastic collision—is one in which the maximum amount of kinetic energy has been lost during a collision, making it the most extreme case of an inelastic collision.

## Is the collision between the ballistic pendulum and the projectile ball elastic or inelastic Why?

On the other hand, in an inelastic collision, momentum is conserved and the two objects stick together after the collision. In the case of the ballistic pendulum, the collision is inelastic because the bullet is embedded in the block.

## How does a ballistic pendulum work?

Ballistic pendulum, device for measuring the velocity of a projectile, such as a bullet. A large wooden block suspended by two cords serves as the pendulum bob. When a bullet is fired into the bob, its momentum is transferred to the bob. The bullet’s momentum can be determined from the amplitude of the pendulum swing.

## What is difference between elastic and inelastic collision?

An inelastic collision can be defined as a type of collision where this is a loss of kinetic energy….Differences between elastic and inelastic collisions.Elastic CollisionInelastic CollisionThe total kinetic energy is conserved.The total kinetic energy of the bodies at the beginning and the end of the collision is different.Momentum does not change.Momentum changes.3 more rows

## Why is the collision inelastic and not elastic?

If the kinetic energy is the same, then the collision is elastic. If the kinetic energy changes, then the collision is inelastic regardless of whether the objects stick together or not. In either case, for collisions with no external forces, momentum is conserved.

## Is a bouncing ball elastic or inelastic?

When a ball is dropped to the ground, one of four things may happen: It may rebound with exactly the same speed as the speed at which it hit the ground. This is an elastic collision.

## What is the difference between elastic and perfectly elastic?

The demand for a good is said to be elastic (or relatively elastic) when its PED is greater than one. In this case, changes in price have a more than proportional effect on the quantity of a good demanded. … Finally, demand is said to be perfectly elastic when the PED coefficient is equal to infinity.
