Fill in the blanks correctly to describe the transfer of energy as a ball falls

Question

Fill in the blanks correctly to describe the transfer of energy as a ball falls down and bounces back up. is converted The ball is dropped and into When the ball hits the ground and comes to a momentary stop, some of the ball's energy is converted into as the ball is distorted by the impact. Some energy is also transformed into As the ball moves back upwards, is transformed into as it falls. of the ball and ground. gravitational potential energythermal energykinetic energyelastic potential energy

Explanation / Answer

a) 1)gravitational potential energy, 2) Kinetic energy, 3) elastic potential energy, 4) Thermal energy, 5) Kinetic energy, 6) gravitational potential energy ----------- note that the answer needs to be continuously filled in the blanks.

b) Situations in which friction will be present or due to impact energy is lost for those cases mechanical energy cannot be conserved.

Case 1) gliding along the ice cannot be completely frictionless as it is not mentioned. so mechanical energy wont be conserved.

Case 2) Moon orbiting the earth:- as there is no any dissipating forces acting onto the bodies hence mechanical energy will be conserved.

Case 3) since the hill is frictionless mechanical energy will be conserved.

Case 4) hill is having friction therefore mechanical energy will not be conserved.

Case 5) surface is not frictionless as well as there is no air resistance hence mechanical energy will be conserved.

Case 6) Ball bounces back to a lower height after the impact so energy is lost during the collision therefore mechanical energy won't be conserved.
