Question

If a body possesses 980 joules of P.E. and 20 joules of K.E., then what is it's total energy?
​

Answer 1

Solution:-

Given➝

P.E. = 980 J , K.E. = 20 J

To find➝

Total Energy ( T.E )

Formula➝

T.E. = P.E. + K E.

Calculation➝

From formula,

T.E. = 980 + 20 = 1000 J

Ans: The body possesses total energy of 1000 J.

Answer 2

Solution:-

Given:

P.E. = 980 J , K.E. = 20 J

To find:

Total Energy ( T.E )

Formula:

T.E. = P.E. + K E.

Calculation:

From formula,

T.E. = 980 + 20 = 1000 J

Ans: The body possesses total energy of 1000 J.
