Question

Clearly Circle your answer 1. The experimentally determined coefficient of restitution depends upon the physical properties of colliding particles. True / False 2. The linear momentum of a rigid body is defined as: L = (12) m v 2 True False 3. Once the particles' velocities before and after the collision have been determined, the energy loss during the collision can be calculated on the basis of the difference in the particles' kinetic energy. True False The conservation of linear momentum equation can be used if the linear impulses are small or non-impulsive. 4. True False During plastic impact, the coefficient of restitution equals 1 because the particles "stick together" but the coefficient equals 0 during an elastic impact because the reactions are equal and opposite. 5. True / False

Explanation / Answer

1, TRUE

Because when soft and hard materials get collision most of the energy will store in soft materials.

2. FALSE

Linear Moment L = m X V

3. FALSE

We use Conservation of momentum. Kinetic Energy use only when collision is elastic.

4. FALSE

Linear moment L = mV = Ft = Linear Impulse... Both are same

5. FALSE

For Plastic Collesion e = 0

For Elastic impact e =1
