• What is the difference between elastic and inelastic collisions?
a) In elastic collisions, kinetic energy is conserved, while in inelastic collisions, kinetic energy is not conserved.
b) In elastic collisions, momentum is conserved, while in inelastic collisions, momentum is not conserved.
c) In elastic collisions, both kinetic energy and momentum are conserved, while in inelastic collisions, neither kinetic energy nor momentum are conserved.
d) In elastic collisions, both kinetic energy and momentum are conserved, while in inelastic collisions, only kinetic energy is conserved.
Answer:
a) In elastic collisions, kinetic energy is conserved, while in inelastic collisions, kinetic energy is not conserved.
Explanation:
In elastic collisions, the total kinetic energy of the system before the collision is equal to the total kinetic energy after the collision. In inelastic collisions, some of the kinetic energy is transformed into other forms of energy, and the total kinetic energy is not conserved.
