Question

7. Two objects with different masses are placed on the same shelf. Which has more potential energy?
A. the object with lesser mass
C. both have the same amount of potential energy
B. the object with greater mass
D. neither has potential energy because they are not moving
​

Answer 1

Answer:

B

Explanation:

the formula for Pe is mass × displacement so more mass more Pe

Answer 2

B. the object with greater mass has more potential energy.

Explanation:

• Potential energy is the stored energy that depends upon relative position of various parts of a system.

• Potential energy is a property of a system and not of an individual body or particle.

• Potential energy is stored in an object due to its position relative to some zero position.

• Potential energy is expressed as:

$P=mgh$

m is mass of object, g is gravitational acceleration and h is the height at which object is placed.

• P is potential energy in Joule.
