What must an object do in order for work to be done?
In order for work to be done on an object, the object must move some distance as a result of the force you apply. There are also constraints on the force you apply. Only force exerted in the same direction as the movement of the object result in work.
When you do work on an object you give it?
For work to be done, the force must be applied in the same direction that the object moves. Work is directly related to both the force applied to an object and the distance the object moves. It can be represented by the equation: Work = Force × Distance.
What is required to do work on an object?
Work In order to accomplish work on an object there must be a force exerted on the object and it must move in the direction of the force. Energy is required to do work and the basic SI unit of energy is the joule, the amount of energy required to exert a force of 1 Newton through a distance of 1 meter (1 joule = 1 newton meter).
What is an example of work done by force?
Work Example. In order to accomplish work on an object there must be a force exerted on the object and it must move in the direction of the force. For the special case of a constant force, the work may be calculated by multiplying the distance times the component of force which acts in the direction of motion.
What determines the amount of force required to lift an object?
The amount of force you exert The distance the object moves Lifting a heavier object demands less or more force than lifting a lighter object. More force Moving an object a shorter distance requires more or less work than moving an object a greater distance
How do you find the work done by a force?
For a constant forceF which moves an object in a straight line from x1to x2, the work done by the force can be visualized as the area enclosed under the force line below For the more general case of a variable force F(x) which is a function of x, the work is still the area under the force curve, and the work expression becomes an integral.
