COEFFICIENT OF RESTITUTION AND CONSERVATION OF LINEAR MOMENTUM
In a perfectly elastic collision, what happens to the total kinetic energy of the system?
What quantity is conserved during any collision, whether elastic, inelastic, or perfectly inelastic?
Which law states that the total momentum of an isolated system remains constant unless acted upon by an external force?
What is the coefficient of restitution (e) for a perfectly inelastic collision?
Which factor could affect the accuracy of experimental results when investigating the conservation of linear momentum and kinetic energy in collisions?
How is the percentage difference in momentum calculated before and after a collision?
What does the law of conservation of linear momentum imply about the total momentum of a closed system?
What type of collision results in a loss of kinetic energy?
What is the purpose of using an air track in collision experiments?
Which of the following equations represents the impulse-momentum principle?
Two gliders collide elastically on an air track. The data are: m1 = 0.5 kg, v1 = 2.0 m/s; m2 = 0.5 kg, v2 = 0 m/s. After collision: v1' = 0 m/s, v2' = 2.0 m/s. What is the total momentum before the collision?
Using the same data as the previous question, what is the total momentum after the collision?
For the collision in the previous questions, which statement is most accurate?
In another experiment: m1 = 0.4 kg, v1 = 3.0 m/s; m2 = 0.6 kg, v2 = 0 m/s. After collision the gliders stick together and move with v' = 1.2 m/s. What type of collision is this?
The coefficient of restitution e is calculated in three trials: Trial A: e = 0.75; Trial B: e = 1.0; Trial C: e = 0.30. Which option correctly matches the type of collision to the value of e?
