You are a police officer who arrives at a scene of an accident. The only evidence that you have is the skid mark left on the road. Fortunately no one gets hurt. The driver indicates that he was not speeding. How could you be sure that he was speeding or not. Explain how you would
calculate and analyze his speed. You can use the formula : W = change in kinetic energy (energy- work theorem).

it doesn't. it was imagined up in the middle ages.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
