Question

Does the kinetic energy of a car change more when it speeds up from 10m/s to 15m/s or from 15m/s to 20m/s?

Answer 1

hi friend,


the change in kinetic energy of car is more in the second case .....since change in kinetic energy is defined as 1/2(mv²-mu²).....where v²-u² is more in the second case .. so, the change in kinetic energy will be more in the second case ....



I hope this will help u ;)

Answer 2

Answer:

kinetic energy is more in second case

Explanation:

we know that kinetic energy equals to 1/2mv2
