During which type of collision do the two objects stick together

Perfectly inelastic collision

Explanation:

There are two types of collisions:

- Elastic collision: in an elastic collision, the total momentum of the objects before and after the collision is conserved; also, the total kinetic energy of the objects before and after the collision is conserved.

- Inelastic collision: in an inelastic collision, the total momentum of the objects before and after the collision is conserved, while the total kinetic energy is not. In fact, part of the total kinetic energy of the objects is lost during the collision, converted mainly into thermal energy (or other forms of energy) due to the presence of frictional forces.

- A particular type of inelastic collision is called perfectly inelastic collision: this occurs when the two objects stick together after the collision. In this case, the maximum amount of kinetic energy of the system is lost.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
