sorry I didn't know the answer

Answer 2

Relation between force , energy and displacement

Explanation:

• It can be clearly seen from the picture that work is done in response to gravity , more importantly against gravity as the bucket is lifted from the well.
• So in this case , work done will be equal to the weight of the object and the vertical distance through which the object is lifted.
• This work done is the same as energy used in the reaction amd will be given as :

Work done = force x displacement

Also we know that ; Force = mass x acceleration

F = m x g [acceleration due to gravity]

Hence,  Work done = mass x acceleration x displacement

Or , W = m x g x h

W = mgh

where m=mass, g=acceleration due to gravity and h=height to which the body is raised )

Incase we need to consider the angle that is made with the direction of displacement , also referred to as theta ( $\theta$ )

Then the expression for energy or work done will be given as :

W= Fcosθ x s

where $\theta$ is the angle between the direction of force and direction of motion.

Fcos$\theta$ = Horizontal component of force F

s = displacement
