Question

An object is moved with a force of 15N across a force 15 Newton across a horizontal surface. How much work is done if the object is moved 50m?

Answer 1

Answer:

750 joules

Explanation:

we know that

w=f.d

so,

f=15N

d=50m

w=15×50

w=750 joules

Answer 2

Work done by the object = 750 Joules ( Newton Metre)

GIVEN:- Force = 15N and Distance = 50 m

TO FIND:- work done by an object

SOLUTION:-

• When force and distance are given then the Work can be calculated with the equation: Work = Force x Distance.
• The SI unit for work is the Newton meter (N m) because One joule is equal to the amount of work that is done when 1 N of force moves an object over a distance of 1 m.

Work = Force x Distance.

By putting values in the formula

$15 \times 50 \\ = 750 \: newton \: metre$

Hence, work done by the object = 750 Joules (Newton Metre)
