Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. In an elastic collision, which of the following quantities are conserved?
Momentum only
Kinetic energy only
Both momentum and kinetic energy
Neither momentum nor kinetic energy
2. What is the defining characteristic of a perfectly inelastic collision?
Objects bounce off each other with no energy loss.
Objects stick together after impact.
Kinetic energy is conserved, but momentum is not.
Momentum is not conserved.
1. The product of an object's mass and its velocity is called .
2. According to the law of conservation of momentum, the total momentum of an isolated system remains .
3. Impulse is defined as the change in .
1. In all types of collisions, kinetic energy is always conserved.
True
False
2. Impulse is a vector quantity.
True
False
1. A 2.0 kg ball moving at 5.0 m/s collides head-on with a 3.0 kg ball moving at 2.0 m/s in the opposite direction. If the collision is perfectly inelastic (the balls stick together), what is their final velocity?
2. A 0.15 kg baseball is thrown with a velocity of 40 m/s. It is hit by a bat, and its velocity changes to 60 m/s in the opposite direction. What is the impulse imparted to the baseball by the bat?
Match the term on the left with its definition on the right.
1. Elastic Collision
a. The total momentum of an isolated system is constant.
2. Inelastic Collision
b. A collision where kinetic energy is conserved.
3. Conservation of Momentum
c. A collision where kinetic energy is not conserved.
Analyze the image of the car collision below and describe two different conservation laws that apply to such an event.
