e=0
The value of the coefficient of restitution in case of a perfectly inelastic collision is e=0.
What is the formula for coefficient of restitution?
v 2−v 1=−e(u 2−u 1). This formula is Newton’s law of restitution. The coefficient of restitution always satisfies 0≤e≤1. When e=0, the balls remain in contact after the collision.
What is the formula for perfectly elastic?
An elastic collision is a collision where both the Kinetic Energy, KE, and momentum, p are conserved. In other words, it means that KE0 = KEf and po = pf. When we recall that KE = 1/2 mv2, we will write 1/2 m1(v1i)2 + 1/2 m2(vi)2 = 1/2 m1(v1f)2 + 1/2 m2 (v2f)2.
What is coefficient of restitution Class 11?
The coefficient of restitution is defined as the ratio of the final velocity to the initial velocity between two objects after the collision. The coefficient of restitution is essentially a measure of the restitution of a collision between two objects that is how much of the energy remains after the two bodies collide.
What is coefficient of restitution give its value?
Answer: Coefficient of restitution is the extent to which a body comes back to its original position after a collision with a second body. Clearly in a perfectly inelastic collision the value of this coefficient is zero as the two bodies merge as one.
What is the value of coefficient of restitution for perfectly elastic collision Class 11?
1
Therefore, the coefficient of restitution for a perfectly elastic collision is 1.
What has the highest coefficient of restitution?
Super Ball
The Super Ball is almost perfectly elastic in both the horizontal and vertical directions. The Super Ball has an almost perfect coefficient of restitution and does things other balls do not.
What is SI unit of coefficient of restitution?
coefficient of restitution has no unit, it is a dimensionless ratio. Explanation: Coefficient of restitution (COR) is the ratio of the relative velocity of an object after collision to the relative velocity of the object before collision. COR generally lies between 0 to 1 for most of the conditions.
