The quantity work has to do with a force causing a displacement. Work has nothing to do with the amount of time that this force acts to cause the displacement.

## Does the work done depend on time?

Work done on an object is the amount of energy changed in the system of an object. And energy is a fundamental thing in physics. Now work is defined to depend directly on displacement and not time.

## What is the formula for work with time?

Important Time and Work Formula Work Done = Time Taken × Rate of Work. Rate of Work = 1 / Time Taken. Time Taken = 1 / Rate of Work. If a piece of work is done in x number of days, then the work done in one day = 1/x.

## How do you calculate work over time in physics?

Work can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton • meter (N • m). One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m.

## What factors affect work explain physics?

There are three key ingredients to work – force, displacement, and cause. In order for a force to qualify as having done work on an object, there must be a displacement and the force must cause the displacement.

## Is work affected by speed?

The work is proportional to the product of the force acting on the object, and it’s displacement in the direction of that force. This means that if you are applying the same force over the same distance, it takes the same amount of work, regardless of the velocity.

## What the work done on an object does not depend on?

d= displacement and 0 is angle between force and displacement. So, the work done on an object does not depend upon the initial velocity of the object. Therefore, the correct answer is Option D.

## Is work equal to force over time?

If the force is constant, work may be computed by multiplying the length of the path by the component of the force acting along the path. To express this concept mathematically, the work W is equal to the force f times the distance d, or W = fd.

## Which of the following does not affect the work done of an object?

Answer:(d) the initial velocity of the object Work done is the product of force and displacement hence force and displacement are the required attributes for the work to be done. But work done is not dependent on initial velocity.

## What is the common formula for work?

It is given as, [ML²T^-²]. Unit of Work: The SI unit for the work is joule (J), and it is defined as the work done by a force of 1 Newton in moving an object for a distance of one unit meter in the direction of the force. Work formula is used to compute work done, force or displacement in any problem.

## Which of the following is correct formula for work done?

Mathematically, the concept of work done W equals the force f times the distance (d), that is W = f. d and if the force is exerted at an angle θ to the displacement, then work done is calculated as W = f .

## How do you find time with Mass and work?

In physics, work = force x distance, so 5.6 N times 7.9 m = 44.24 joules. How do I calculate the work done if the body of mass 80kg is lifted vertically through a distance of 5.0 m? Work is equal to the force into displacement, i.e. here the work would be 40 joules.

## How do you calculate work when force is not given?

## How do you calculate the work done on an object when you push it?

The work W done on an object by a constant force is defined as W = F·d. It is equal to the magnitude of the force, multiplied by the distance the object moves in the direction of the force.

## What are the 2 variables that affect work physics?

The acting force and the displacement in the direction of the force are the two conditions for work to be performed in physics.

## On what factors does work depend?

Solution : Work done by a force depends on (i) magnitude of force (ii) magnitude of displacement (iii) angle between force applied and displacement .

## What are the two factors needs to describe work?

Work is the product of the component of the force in the direction of the displacement and the magnitude of this displacement.

## Does faster mean more work?

If work is done faster, power is higher. If work is done slower, power is smaller.

## Does work done depend on acceleration?

So, From the expression of work, it is very clear that the work done depends upon, the applied force, displacement and angle between them. It does not depend upon the initial velocity of the object.

## Does initial velocity affect work?

No, work done on an object doesn’t depend on the initial velocity of the object. Q. An object of mass, m is moving with a constant velocity, v.

## What are the condition of work done?

The two conditions are: i Application of-force on the body. ii Displacement of the body in the direction of force.

## Which quantity does not depend on time work energy or power?

Energy spent does not depend on time but power depends on time in which the energy is spent.

## When work is done on an object it changes the object’s?

Key terms. Net work done on an object equals the object’s change in kinetic energy. Also called the work-energy principle.

## What is work done over time?

Power is mathematically defined as the work done divided by the time taken. Since Work done / Time taken = Power, and Displacement / Time taken = Velocity, we can simplify the formula to: Formula: Power = Force (N) x Velocity in the direction of the force (m/s)

## How do you define work in physics?

In physics, work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, it is often represented as the product of force and displacement.
