Question

A ball is allowed to roll down an inclined wooden plane from a given height at the foot of the inclined plane, differently 'covered' one by one ,

In which case , is the ball likely to move the longest distance? Give reason for your answer .

Answer 1

HEY MATE!!!!

The ball which is kept higher will be likely to move the longest distance because the POTENTIAL ENERGY Which is directly proportional to the height of the object is more in the higher level.

Since the body's motion is only under the influence of the gravity the conservation of energy is must.

So higher the potential energy higher the kinetic energy and if the kinetic energy is higher than the velocity will be higher with results in more displacement

Answer 2

Answer:

the ball likely to move the longest distance in the 'case 3'.

Explanation:

because glass sheet have less friction due to plane surface.
