Answer 1

Answer:

Energy is the ability to work is known as energy.

It S.I unit is joule.

It is a scalar quantity.

Answer 2

Explanation:

Energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another.

the SI unit for energy is the same as the unit of work – the joule (J), named in honor of James Prescott Joule and his experiments on the mechanical equivalent of heat. In slightly more fundamental terms, 1 joule is equal to 1-newton meter and, in terms of SI base units

1\ {\mathrm {J}}=1\ {\mathrm {kg}}\left({\frac {{\mathrm {m}}}{{\mathrm {s}}}}\right)^{2}=1\ {\frac {{\mathrm {kg}}\cdot {\mathrm {m}}^{2}}{{\mathrm {s}}^{2}}}
