What is the most likely evidence of an energy transformation taking place when a skater glides over ice? skating blades become cold as kinetic energy is transformed into thermal energy skating blades become cold as kinetic energy is transformed into gravitational energy small tracks of water are left on the ice as kinetic energy is transformed into thermal energy small tracks of water are left on the ice as kinetic energy is transformed into gravitational energy

Small tracks of water are left on the ice as kinetic energy is transformed into thermal energy

Explanation:

Here when we see the evidence of energy transformation then we can say that when skater glides over the surface of ice then due to friction between the skates and the ice surface it generates heat

Due to this heat few of the ice will melt down and it converts into water

So here the energy transformation is in following way

first kinetic energy of the skater will convert into frictional work done

this frictional work will generate heat

due to heat it will convert the ice into water

so correct answer will be

Small tracks of water are left on the ice as kinetic energy is transformed into thermal energy

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
