Explanation:
Detailed explanation-1: -Doubling the velocity would have a greater effect on the kinetic energy of an object because the formula contains the square of velocity.
Detailed explanation-2: -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-3: -Kinetic energy depends on the velocity of the object squared. This means that when the velocity of an object doubles, its kinetic energy quadruples.
Detailed explanation-4: -2. It is clear that the kinetic energy of a body depends on two factors: Mass and velocity of the body.
