Physics · Collisions
In an elastic collision between two bodies of equal mass, during the exact period of maximum deformation/impact, which of the following statements is true regarding kinetic energy?
- 1The total kinetic energy is completely conserved at every instant of the collision.
- 2The total kinetic energy is maximum at the moment of maximum deformation.
- 3A portion of the kinetic energy is temporarily converted into elastic potential energy, so total kinetic energy is not conserved during the deformation phase.✓
- 4The kinetic energy of the system becomes zero during the collision.
Correct answer
A portion of the kinetic energy is temporarily converted into elastic potential energy, so total kinetic energy is not conserved during the deformation phase.
