An object is removed from the ground and placed on a shelf. Which of its properties would you expect to change?
|
|
Mass
|
|
|
Volume
|
|
|
Potential Energy
|
|
|
Kinetic Energy
|
Explanation:
Detailed explanation-1: -We say that gravitational potential energy is zero when the object is on the ground(earth surface).
Detailed explanation-2: -When the object hits the ground, its kinetic energy gets converted into heat energy and sound energy.
Detailed explanation-3: -As an object falls from rest, its gravitational potential energy is converted to kinetic energy. Conservation of energy as a tool permits the calculation of the velocity just before it hits the surface.
