Explanation:
Detailed explanation-1: -The two main factors that affect kinetic energy are mass and speed. Why? Because the motion of an object depends on how fast it’s traveling, but also how much mass it has, though velocity is the more important factor.
Detailed explanation-2: -Explain that there are two factors that affect how much kinetic energy a moving object will have: mass and speed.
Detailed explanation-3: -Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
