the last one which is D

As an acorn falls from a tree toward the ground, gravitational potential energy is converted into kinetic energy.

To find the correct option among all the options, we need to know about the conversation of energy.

How are the gravitational potential energy and kinetic energy defined near the earth surface?

  • Near the earth surface, the gravitational potential energy is given as mass×g×height from the earth surface.
  • Kinetic energy is given as 1/2×mass×velocity².

How are the gravitational potential energy and kinetic energy converted when acorn falls from a tree?

  • When an acorn is going to fall, it is at maximum height of its journey, so it has maximum gravitational potential energy.
  • Also, at that time, its kinetic energy is zero as it's at rest.
  • But when it moves down, its potential energy decreases as the height decreases and kinetic energy increases due to increasing velocity. So that its total mechanical energy is conserved.

Thus, we can conclude that option (d) is correct.
