2 cars are lifted to the same elevation in a service station. If 1 car is twice as heavy as the other, how do their potential energies compare?
once you throw a ball up into the air its kinetic power gradually decreases with time as gravity pulls it right down to earth till all of its kinetic power has been converted to skill power. this implies the kinetic power of the ball is at a optimal on the instantaneous the ball is thrown and likewise on the instantaneous in the previous it hits the earth (after it has fallen). the aptitude power of the ball is proportional to its top. this implies that once the ball is at its optimal top above the earth, it additionally has its optimal skill power.
potential energy of car mass*acceleration due to gravity*height acceleration due to gravity and height are same for both cars so they PE are measures of their masses PE1:PE2m1:m2 2:1
Potential energy mgh g is a constant and h is equal for both cars. If the mass of car 1 is twice as much as the mass of car 2, the potential energy for car 1 will be twice as much as the potential energy for car 2.
