Answers
Answer:
Quite often we use terms such as overworked and hard worker to describe the quantity of effort put by a person. But what is the meaning of work and how do we quantize it? In this section, we will learn about the physical meaning of work and the factors on which it depends. We can define work as:
The product of the component of the force in the direction of the displacement and the magnitude of this displacement.
Work Formula
Mathematically we can write,
W = (F cos θ) d = F. d
Where,
W is the work done by the force.
F is the force, d is the displacement caused by the force
θ is the angle between the force vector and the displacement vector
Work dimension is the same as that of energy and is given as, [ML^2T^–2].
Answer:
Work is force applied over a distance.
Examples... Lifting an object, Driving a car on a hill, pushing an object against frictional force.
