A sparrow and a crow are having the same kinetic energy during a flight. Which of the two is moving fast and why?
As we know, K.E=12×m×v2
where,
K.E=KineticEnergym=massv=velocity
Explanation:
Thus, the sparrow is moving fast.
Two toy-cars A and B of masses 200 g and 500 g respectively are moving with the same speed. Which of the two has greater kinetic energy ?
A bus and a car have the same kinetic energy. Which of the two is moving fast? Explain
a) How is the kinetic energy of a moving train affected it its velocity becomes one third?
b) A car and bus are moving with the same speed. which one has more kinetic energy? explain
