Question

Which has a greater effect on the kinetic energy of an object: mass or velocity? Why?

Answer 1

Velocity

Explanation:

We know that in Classical mechanics,
Kinetic energy `KE=1/2 "mass"*"velocity"^2`
From this expression we see that

`KE prop "mass"`
i.e., Kinetic energy is directly proportional to the mass.

Also `KE prop "velocity"^2`
i.e., Kinetic energy is proportional to the square of the velocity.

Hence, the answer.
