Question

Show that the sum of potential energy and kinetic energy remains the same by giving the example of roller coaster car​

Answer 1

Answer:

I would love if you liked my answer

Explanation:

so we can understand the mechanical energy is always constant so the rollercoaster moves but doesn't stop until we cut energy source to it

Answer 2

Answer:

Roller coaster operates on the law of conversion of energy. essentially some work is done to put the roller coaster car at the top position. this work done is stored in the roller coaster car in the form of potential energy but its kinetic energy is zero due to stationary position as it starts coming down from top position and its height start decreasing so its potential energy decreases and the kinetic energy increases. hence potential and kinetic energy remains same.

Hope my answer is correct
