A. Mass
B. Density
C. Elasticity
D. Height

Answer 1

Answer:

mass.......

k.E=1/2mv^2

Answer 2

Answer:

The ‘mass of the object’ directly affects kinetic energy.

Explanation:

• Along with the mass of the body, the speed at which it is moving also affects the kinetic energy because kinetic energy is the ‘energy possessed’ by the body when in motion.
• When the mass of the body is increased, the kinetic energy will also be increased.
• Other factors like density, elasticity and height also affect kinetic energy. As the body falls from a height h, the potential energy gets decreased and due to ‘the gravitational force’, the kinetic energy will increase.
• With elasticity the kinetic energy is conserved. As the density increases the kinetic energy also will increase.
