During a race, you are accelerating on a leveled track and acquired a velocity 3 times your initial velocity. What was the change in your potential energy?
It does not change.
Potential energy is mathematically represented by the formula,
P.E. = m ×g×h,
where m is the mass,
g is acceleration due to gravity and
h is the height in meters.
As you are running on a leveled track, there is no change in potential energy because there is no change in the height of the body from the ground.
