No. Potential energy is STORED enegry. Potential energy can be measured in footpounds, that is the number of pounds x the hieght it is from the ground. For example, if you drop a car off a jack, it probably won't hurt the car. If you drop the same car off the back of a truck, it will cause minor damage. If you drop it out of an airplane total destruction. If you double the height, it will double the potential energy.
