Question

As a skater descends his kinetic energy

Answer 1

what r u meaning

Answer 2

I mean if a Skater decends, how is his kinectic energy affected??? Does it icrease decreas or remain the same????

Answer 3

it decreases

Answer 4

What happens to his potential energy.. and is the change in kinetic energy greater than less than or equal to the change in potential energy...

Answer 5

descends in what sense? You mean falls vertically?

Answer 6

As just about anything falls, it increases speed and hence increases kinetic energy

Answer 7

And where does that energy come from? It comes from gravity. As the skater falls, he loses gravitational potential energy, nearly all of which is converted into kinetic energy.

Answer 8

so the kinetic energy would rise and the potential energy would fall right...

Answer 9

Yes

Answer 10

Is it possible for an object moving with a constant speed to accelerate

Answer 11

A girl pulls a 10-kg wagon with a constant force of 30 N. What is the acceleration of the wagon?

Answer 12

everything is possible

Answer 13

Assuming this skater doesn't fall, her velocity will increase, thus her kinetic energy will increase according to the equation:\[KE = 1/2 mv ^{2}\]

Answer 14

yes. a body having the modulus of velocity as constant may accelerate. consider a body moving with constant speed in a curved path. the direction of the body is continuously changing and thus velocity continuously changes which is nothing but acceleration.
