Question

1.A force of 25N is acting on an object. The object is displaced through 8 m in the direction of the force. calculate the work-done.​

Answer 1

Given:-

• Force ,F = 25 N

• Displacement ,s = 8m

To Find:-

• Work done ,W

Solution:-

As we know that work done is defined as the product of force and displacement.

• W = FS

Substitute the value we get

→ W = 25 ×8

→ W = 200 J

Therefore, the work done is 200 Joules.

Additional Information!!

•Product of mass and acceleration is called force.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀OR

•A push or pull of an object is called force.

✧ SI unit of Force is Newton.

✧ It is denoted by N.

✧ Force is vector Quantity i.e., both Magnitude and direction.

✧ Mathematical term

⟹ Force = Mass×Acceleration

Answer 2

$\huge\sf\underline\red{Required answer}$

Given,

F=25N

S=8M

Work done =?

We know that W=FS

Plugging the values

W=25×8

W=200J

Therefore Work done by body is 200J
