Question

Define work done by constant force. also define its unit. Calculate work done if 140N of force produces a displacement of 250cm.​

Answer 1

Answer:

.......................

Answer 2

Answer:

"Work done by a Force is the product of the force and the distance moved bu the force in the direction of force''

UNIT OF FORCES:

The unit of work is joules(J)

1J=1Nm

''One joule is the work done by the 1N force and THE DISTACE OF 1m, the direction along which the mass moves.''

• THE WORK DONE BY 140N AND DISPLACEMENT OF 250CM IS:

SOLUTION:

1METRE=100CM

2.5METRE=250CM

WORK DONE=FORCE APPLIED×DISPLACEMENT COVERED

                     =140×2.5

                    =350Nm.

the work done is 350Nm.
