1. What do you mean by energy ? 2. What is the S. I. unit of energy ?

3. Name the different types of energy .

Help me please !! It's easy .

1. The ability of a body to do a work is called energy.

2. The S.I. unit of energy is joule(J).

3.The different types of energy are :

Explanation:

answer would be d.) i hope this

explanation:

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
