Answer :
Answer:
Work is a measure of the energy transferred and required a force acting on an object and displacement of the object
Explanation:
Work is a measure of the energy transferred to an object when a force is applied to the object.
Mathematically, work is defined as
[tex]W=Fd cos \theta[/tex]
where
F is the magnitude of the force applied on the object
d is the displacement of the object
[tex]\theta[/tex] is the angle between the direction of F and d
We notice from the formula that:
- When the object is not moving, the displacement is zero, so no work is done
- The work done is maximum when the force is parallel to the displacement, [tex]\theta=0^{\circ}[/tex], and zero when the force is perpendicular to the displacement, [tex]\theta=90^{\circ}[/tex].
