How is the peak force of a collision related to the kinetic energy of the objects involved?
How is the peak force of a collision related to the kinetic energy of the objects involved?
- Higher kinetic energy results in higher peak forces. (correct)
- There is no relation between kinetic energy and peak forces.
- Higher kinetic energy results in lower peak forces.
- Lower kinetic energy results in higher peak forces.
