Question
What is the value of the kinetic energy when the velocity of the object is
18 Km/h
- 500J
- 2000J
- 4500J
- 8000J
Hint:
According to the graph given, the velocity is directly proportional to the kinetic energy. If the velocity is 1800 Km/h, the kinetic energy is 500 J.
The correct answer is: 500J
- The kinetic energy changes according to the increase or decrease in velocity.
- The graph show the increase in the kinetic energy according to the increase in velocity.
- The kinetic energy is 500 J when the velocity is 1800 Km/h.
