The potential energy in the energy an object has due to its A man B. motion C. position D. weight 3. The following conditione exhibits kinetic energy EXCEPT: A. water inside a place B. rolling stone from the hill C. running athlete on the field D, dancing leide in the living room of the house 4. Which of the following quantities, when doubled, has the greatest effect on the amount of kinetic energy? A maos B. size
The following situations demonstrate potential energy EXCEPT a car parked at the top of a hill. Letter C.
The potential energy is the energy an object has due to its MOTION. Letter B.
The following conditions exhibit kinetic energy EXCEPT WATER INSIDE A GLASS. Letter A.
SPEED has the greatest effect on the amount of kinetic energy when doubled. Letter C.
If a green ball is higher from the ground than a yellow ball and both have the same mass, GREEN BALL has more potential energy. Letter A.
Explanation:
Potential energy is that the latent energy in an object at rest, and is one among two types of energy.
The potential energy of any given object may be a measurement of its potential to try and do work, create heat and generate power.
For this reason, the calculation of an object's potential energy is that the sum of its mass, distance from the world, electrical charge, distance from other objects, and internal elastic forces (that is, any internal mechanical force).
Formula
Potential Energy = mgh
m is the mass (kg)
g is the acceleration due to gravity (9.8 m/s^2 at the surface of the Earth)
