a meteor Falls towards Earth's surface given that the acceleration due to gravity is 9.8 m/s^2 what is the meteors potential energy if it has a mass of 20kg at an altitude of 500

This is what i found on google “according to the collision theory, the following criteria must be met in order for a chemical reaction to occur: molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break. molecules must collide with the proper orientation.” i hope this information you.
