In which case is the work done?

In which case is the work done?

When the direction of force is similar the direction of motion, and hence, the work done is maximum.

In which of the following cases in the work done positively?

As suitcase falls down, it displaces in downward direction and force of gravity also acts in the same direction. => Work done by gravity force is positive. When Porter stands on the platform with suitcase in his head,then there is no moment in suitcases. So, work done by Porter on suitcase is 0.

What are the types of work done give an example of each?

(1) When a spring is stretched, the work done by the stretching force is positive as the force acts in the direction of displacement of the spring. (2) When a body falls freely under gravity, the work done by gravity is positive as force (gravity) and displacement of the body are in the same direction.

What is work done by force give an example?

Work Done Examples Positive Work: If a force relocates the object in its direction, then the work done is positive. The example of this type of work done is the motion of the ball dropping towards the ground where the displacement of the ball is in the direction of the force of gravity.

In which scenario is work being done on an object?

When an object moves while a force is being exerted on it, then work is being done on the object by the force.

What is your basis in choosing a situation where work is done?

Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work.

Is work done positive or negative?

Work done by a force applied on a body is: When the direction of motion of the body and the force acting on the body is opposite, work done is negative.

How to describe a difficult situation at work?

Try to narrate a situation with a happy ending. Ideally it should be a story they can remember. Add some numbers and facts in order to make it sound credible. And if you are applying for your very first job, you can always tell them what you would do in a difficult situation (one you will likely face in your new job).

How to answer ” what type of work environment do you prefer “?

Employees who mesh well with the company’s environment will be happier and, in turn, stay in the job longer and contribute more. So answering the question is simple, right? Just tell the interviewer that your preferred environment matches up perfectly with the company’s environment.

How to get a sense of the work environment?

There’s no better way to get a sense of the work environment and culture than from the employees themselves. This could take the form of an informational interview. Or if you were referred to the company by someone you know, be sure to talk to them about what it’s like to work there.

Is there a connection between work and energy?

There is a strong connection between work and energy, in a sense that when there is a net force doing work on an object, the object’s kinetic energy will change by an amount equal to the work done: Note that the work in this equation is the work done by the net force, rather than the work done by an individual force.
