What is the difference between an inelastic and perfectly inelastic collision?
What is the difference between an inelastic and perfectly inelastic collision?
An inelastic collision, in contrast to an elastic collision, is a collision in which kinetic energy is not conserved due to the action of internal friction. A perfectly inelastic collision occurs when the maximum amount of kinetic energy of a system is lost. …
When two objects collide and stick together what will happen to their speed assuming momentum is conserved?
When two objects collide and stick together, what will happen to their speed, assuming momentum is conserved? They will move at the same velocity as whichever object was fastest initially. They will move at the same velocity of whichever object was slowest initially.
What happens in a perfectly inelastic collision?
A perfectly inelastic collision occurs when the maximum amount of kinetic energy of a system is lost. In a perfectly inelastic collision, i.e., a zero coefficient of restitution, the colliding particles stick together. In such a collision, kinetic energy is lost by bonding the two bodies together.
What happens in an 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. This is because some kinetic energy had been transferred to something else. Such collisions are simply called inelastic collisions.
Which of the following is not an example of perfectly inelastic collision?
In ball bearing striking another ball bearing momentum of the balls system is conserved. Therefore it is not an example of perfectly inelastic collision.
Which of the following is not correct for inelastic collision?
Step by step solution: In an elastic collision kinetic energy and momentum are conserved. But in an inelastic collision only momentum is conserved kinetic energy is not conserved. So we cannot apply the law of conservation of kinetic energy in the case of inelastic collision.
Which is more elastic rubber or steel?
If the same amount of force is applied to a steel wire and to a wire made of rubber of same length and cross-sectional area, the extension of rubber wire is easier than the extension of the steel wire. Therefore, with the help of Young’s modulus, it can be concluded that steel has greater elasticity than rubber.
Which is more elastic rubber or glass?
(a) Glass is more elastic than rubber because for a given applied force per unit area, the strain produced in glass is much smaller than the strain produced in rubber.
Can a body be perfectly elastic?
A body whose momentum , kinetic energy and total energy are conserved is called perfectly elastic body. a perfectly elastic body is the one which can completely regain its shape after it is being deformed or after the deforming force is removed.
Is there a perfectly elastic body give an example?
Answer. Quartz fibre and Phosphor bronze are the examples of perfectly elastic body.
Under what condition is a body said to be perfectly elastic?
A body is said to be perfectly elastic if it recovers its original shape/size when the deforming force is removed.
Why is no material perfectly elastic?
This is because for a material to be perfectly plastic it should be able to get elongated infinitely but no material can be stretched infinitely. If we stretch any material then it is sure that it will break at some moment, so no material is perfectly plastic.
Which of the following material is more elastic?
rubber
