What else can I help you with?
What happens when a force moves an object over a distance?
Work
Is work done if you push a car that has run out of gas?
Yes. The work is being done by whoever is pushing rather then the engine, but work is being done. Any time a force is applied through a distance, work is being done.
If effort is applied and nothing moves is work done?
No work because no change in position occurs.
Why when you push an object across a desk the work done is not equal to the change in gravitational potential energy?
In this case, you are not doing work against the force of gravity, but against the force of friction.
Is physical work requiring energy being done if a person pushes on a locked door?
Yes because work is using energy to move something. Anytime we push-pull, work (energy) is used.
If you push on a box but the box moves backward you have done work.?
Yes.
If you push an object at an angle so that the object moves along the ground how much your push counts as work?
All of it is counted as work.
If you push on a box but the box moves backwards what kind of work is being done?
Negative work is being done when you push on a box but it moves backwards. This means that the force you apply is in the opposite direction of the displacement of the box, resulting in a decrease in its energy.
If you push a box forward and the box moves forward you have done work.?
Work, more specifically "positive" work because the box moved in the direction in which the force was applied.
If you push a box forward and the box moves forward you have done how much work?
You have only done as much external work on the box as the distance it moves: work = force x distance. If it does not budge no work is done on the object. You have done "internal" work on your muscles which converts to heat energy, but technically speaking, no external work is done on the object
What is he definition of work?
Work is the product of a force and the distance through which it acts in the direction of the force. In order for work to be done, the object must move in the direction of the force. If you push on a brick wall until you exhaust yourself and the wall doesn't move, you have not done any work. If you push on a box and it moves in the direction that you are pushing it, you have done work.
-True or false work is force applied over a distance?
Work = Force times displacement The work done on an object is equal to the Force (push/pull) on the object in Newtons times the distance (in meters) that the object moves. If you push or pull on an object and it does NOT move (zero displacement), then no work is done on the object.
How can work be done?
Work done when force moves an object.
If you push an object at an angle so that the object moves along the ground how much of your push counts as work?
Only the component of the force in the direction of the motion of the object counts as work. Work done is defined as the force applied in the direction of the displacement multiplied by the displacement. Perpendicular forces do not contribute to the work done on the object.
If you push on a large box and it moves zero meters how much work is done?
No work is done because work is defined as force applied over a distance, and in this case, the box did not move any distance. Therefore, the work done is zero.
Why would a cart start moving faster if you gave it hard push than if you gave it a soft push?
When u push the cart,u apply some force on the cart which does the work(the cart moves). The movement of the cart is the work done due to the application of the force you.
If you push a box forward and the box moves forward what type of work have you done on it?
When you push a box forward and it moves forward, you have done positive work on it. This is because you applied a force in the direction of its displacement, resulting in the box moving in the same direction as the force applied, indicating positive work.
