What two characteristics of objects impact kinetic energy the most?

Question 3 options:

mass and weight

velocity (speed) and distance

mass and velocity (speed)

mass and distance

mass and velocity (speed)

Explanation:

Kinetic energy is the energy possessed by a body due to its motion, e.g a moving car. It is measured in joules.

Thus, Kinetic energy = 1/2 x (Mass x velocity^2)

For instance:

A moving car that has a mass of 10 kg and runs with a velocity of 2m/s will have a kinetic energy of 20 joules.

Thus, the mass and velocity (speed) of an object impact kinetic energy.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
