Forces only do work if they move things. You could push on a brick wall all day but you would still not do any work. If you stand still, your feet are pushing on the ground, but you are not doing any work, You could be asleep.
So, forces only do work if they move and actually do something.
In cases where you might say that only half of a force did work, then it's best to say that you have two forces. One that did work and one that did nothng.
In cases where a force has only done half the work, then you would have to wait for that force to finish the other half, or get a new force.
What else can I help you with?
Why are you doing work when you lift something but not when you carry it?
Its just due to the "physical" definition of work. In order for a force to do work on an object it must move (at least some component of it) parallel to the force. So when lifting, the force is up and the movement is up and the force does work. In carrying, the force is up but the movement is horizontal. They are perpendicular and the force does no work. False
How do forces work in different directions?
You calculate the vector sum of all the forces acting on the object. For example, if one force is in the positive direction, say 8N, and another force is in the opposite direction, say -7N, the net force would be 8N + (-7N) = 1N.
How are mass and distance related to the gravitational force?
The exact relationship is given by Newton's law of universal gravitation: F=G*m1*m2/R**2, where G is a constant that applies to all matter; m1 and m2 are the masses of the two attracting bodies, respectively; and R is the separation between their centers of gravity.
What happens when a force moves an object over a distance?
Work
160j of work was needed in order to move an object 8m across the floor what was the force in N that was needed to do this job?
Work = Force * Displacement. Therefore Force = Work / Displacement = 160 J / 8 m = 20 N (Note that the force and the displacement have to be in the same direction, or else the components of either of them will have to be calculated in the direction of the other)
What is a work force?
A work force is a collective term for all of the workers employed by an organization or state or to complete a specific project.
Is work a force?
A work force is a collective term for all of the workers employed by an organization or state or to complete a specific project.
What is work force?
A work force is a collective term for all of the workers employed by an organization or state or to complete a specific project.
How can work be calculated when force and motion are parallel to each other?
Work can be calculated as the product of the force applied and the displacement in the direction of the force. When the force and motion are parallel to each other, all of the force contributes to the work done because the angle between the force and displacement is zero. So, the work done is simply the force multiplied by the displacement.
can your employer force you to work off of the clock as an hourly employee?
No. By law no employer can force you to work at all, especially without payment.
If force is 5 newton and displacement is zero then?
If what you want to do is calculate the work, you need to multiply the force times the displacement.
Do all forces of an object cause work to be done?
No, work is only done by a force when there is displacement in the direction of the force. Forces that do not cause any displacement, such as static friction or normal force, do not do work on an object.
How do you work out the movement of force?
Balance the force on all direction and after all cancellation, the remain force give the direction the object go. For matter of speed and acceleration, check it mass and find out the acceleration from force.
IS THERE work can be done without any force?
No, work cannot be done without any force being applied. In physics, work is defined as the product of the force applied to an object and the distance over which the force is applied. Therefore, without force, there is no work being done on an object.
What do muscles do all day?
Work! w=force times displacement.
What is a force exerted over a distance to move an object?
all forces are either a push or a pull. even over a distance. gravity is a pull and its opposing force, upthrust, is a push or for ipc its work
If force is work divided by distance then distance is force divided by work?
I usually start with the definition of work: Work = force * distance so... Force = work / distance Distance = work / force So, no. You had it backwards.
