In everyday popular usage, "work" means effort, sweat, things like that. But the formal
scientific definition of work is: (Force) times (distance). You can push on a brick wall as
hard as you want for as long as you want; no work has been done until the wall moves,
because the force hasn't moved through a distance.
What else can I help you with?
What is a example of doing work?
An example of doing work is lifting a box from the floor to a shelf. In this scenario, you are exerting a force to move the box against the force of gravity, thereby performing mechanical work on the box.
When you push you are doing friction gravity or work?
When you push an object, you are doing work. Work is the transfer of energy that occurs when a force is applied to an object, causing it to move in the direction of the force. Pushing involves exerting a force on an object to move it.
A spring clamp exerts a force on a stack of papers it is holding together Is the spring clamp doing work on the papers?
Yes, the spring clamp is exerting a force on the papers, but it is not doing work on them unless the papers are displaced in the direction of the force. Work is only done when a force causes a displacement in the direction of the force.
Did exerting force always do work?
yes sometimes
Is climbing a ladder doing work?
Yes, climbing a ladder involves doing work because you are exerting a force against gravity to lift your body upward. Work is defined as the product of the force applied and the displacement in the direction of the force. In this case, as you climb, you apply a force to overcome your weight and move vertically, resulting in work being done.
In the force has a component in the opposite direction from the motion the work done is negative?
No the work done is still positive, the force exerted and the work done to exert that force is still the same. Its just that the other object is exerting more of a force on the object doing the work.
How you can exert a large force on an without doing any work?
You can exert a large force on an object without doing any work by exerting the force perpendicular to the direction of motion. In this case, no work is done because the force does not act in the direction of the object's displacement. This situation is commonly seen in scenarios involving static friction or when lifting an object vertically.
If your friend pushes a lawn mower four times as far as you do while exerting only half the force which one of you does more work?
You friend would be doing twice as much work as you. Work=Force x Distance. Therefore, if he's doing .5 force x 4 distance, his work is 2, while yours would only be 1 (1 force x 1 distance).
A truck pull a trailer 100 m while exerting a force of 480 newtons what is the work done by the truck?
The work done by a truck pulling a trailer for a distance of 100 M while exerting a force of 480 newtons is 48000 newtons.
If you were pushing very hard against a brick wall would you be doing work?
Yes, pushing against a brick wall would require force and displacement, which are the two components of work. You would be exerting energy to apply a force on the wall, but if the wall doesn't move, there would be no work done on the wall.
When you push a cart at the store are you doing work and How do you know?
Yes, pushing a cart involves doing work because you are exerting a force to move an object over a distance. You can know this by observing that your muscles are actively working to apply force to the cart and move it from one point to another.
When you set a heavy bag down on the ground you are work on it?
Negative
