Mass is a measure of the amount of matter in a substance or an object.
Answer: Two glass marbles bounce off each other.
Explanation:Elastic collisions are collisions in which both momentum and kinetic energy are conserved. The total system kinetic energy before the collision equals the total system kinetic energy after the collision. If total kinetic energy is not conserved, then the collision is referred to as an inelastic collision.
An elastic collision occurs when the two objects "bounce" apart when they collide. Two rubber balls are a good example. In an elastic collision, both momentum and kinetic energy are conserved. Almost no energy is lost to sound, heat, or deformation.
Answer:
Potential energy in the system = 1,500 J
Explanation:
Given:
Total energy of a system = 2,000 J
Kinetic energy = 500 J
Find:
Potential energy in the system
Computation:
Total energy of a system = Kinetic energy + Potential energy
2,000 J = 500 J + Potential energy in the system
Potential energy in the system = 1,500 J
