1) What is kinetic energy?
2) What will happen to the kinetic energy of a body if it's velocity is doubled?
3) Name 4 units of energy.
4) In a tug of war, one team gives way to others. What work is being done and by whom? ​

Answer 1

Ans 1. energy which a body possesses by virtue of being in motion.

Ans 2. The kinetic energy is proportional to the square of the velocity. ... Because when velocity is doubled, the kinetic energy will be become two times of velocity.

Ans 3. 1Barrel of oil.

2 Calorie.

3 Horsepower.

4 Joule (J)

Ans 4. Work is being done by the winning team. Work done = resultant force applied by the two teams x displacement of the loosing team.

Answer 2

Answer:

1) the energy possessed by a body by by virtue of its motion is called kinetic energy examples include such as a moving ball flowing water a flying bird

2) if the velocity of kinetic energy is doubled in a body to be like as the body posses more kinetic energy

3)
