Does force and energy work together?
Energy has dimensions of force times distance. If a force moves an object, then work was done and work is a form of energy.
What is accomplished when an object is moved by force?
Work is done when a force acts on an object as the object moves from one place to another. Work is defined as force times distance.
Which activity describes work being done on an object?
A person pushing a box across a floor:· Mass of box = 20 KG, Weight of Box = 196.2· Distance moved in the direction of the force = 2m· Work Done = Force X Distance ( in the direction of the force), 196.2 X 2= 392.4 Joules
What must occur for work to be done on an object?
Formally, energy is required to do work. Work is technically force times distance. Thus, what must occur is a force must be applied to an object and the object must move with some movement being in the direction of the force. The quantity of work done is the "dot" product of the force vector and displacement vector. To carry out work "on an object" or in any fashion requires the same amount of energy be used as the amount of work done. (Of course, friction and other inefficiencies result in the use of more energy than the actual work done, with the excess energy taking some other form, such as heat.)
Define potential energy and kinetic energy?
kinetic- work done by an external force from bringing the object to a rest then to movementpotential- unknown sourcekinetic energy is the energy or force of any motion, and everything, whether it is object, particles, molecules or person has motion. Everything that is moving, either by their own force or by any other force is considered to have kinetic energy.
Energy of an object increases when what is done on the object?
When force is done on the object
What is necessary for force to be done?
transferring energy to or from an object by applying a force over a distance.
Does force and energy work together?

How much work is done with 200N of force in unsuccessful effort?
Work = force x distance. If the object doesn't budge, no energy is transferred (no work is done). Some energy may be wasted, but no work is transferred.Work = force x distance. If the object doesn't budge, no energy is transferred (no work is done). Some energy may be wasted, but no work is transferred.Work = force x distance. If the object doesn't budge, no energy is transferred (no work is done). Some energy may be wasted, but no work is transferred.Work = force x distance. If the object doesn't budge, no energy is transferred (no work is done). Some energy may be wasted, but no work is transferred.
What is accomplished when an object is moved by a force?
When an object is moved by a force, work is done, increasing or decreasing its kinetic energy, often but not always decreasing or increasing its potential energy.
What is accomplished when an object is moved by force?
Work is done when a force acts on an object as the object moves from one place to another. Work is defined as force times distance.
What is the definition of work'?
Is done when a force exerted on an object causes that object to move some distance; equals to force times distance; measured in joules (j)

Is chemical energy potental or kinetic energy?
Chemical energy is a kind of potential energy - energy related to the position, or more accurately, work done to move an object against a conservative force.Chemical energy is a kind of potential energy - energy related to the position, or more accurately, work done to move an object against a conservative force.Chemical energy is a kind of potential energy - energy related to the position, or more accurately, work done to move an object against a conservative force.Chemical energy is a kind of potential energy - energy related to the position, or more accurately, work done to move an object against a conservative force.
What is the evidence for determining whether or not work is done on an object?
Basically if the energy of the object has changed. For example if you lift something off the ground you have applied a force through a distance in the same direction as the force. By lifting the box you have given it gravitational potential energy (mgh). If you drop the box then gravity does work because the force of gravity will apply a force through a distance in the same direction. Just because there is force, doesn't mean work has been done. For example if you look at uniform circle motion even though there is a force, known as centripetal force, there is no work being done. This is because centripetal force is always perpendicular to velocity and only components of force parallel to the object can do work on it. We can tell no work has been done because the kinetic energy of the object remains the same (=1/2*m*v2).
Is holding an egg mechanical energy?
No mechanical energy is needed to hold up an object. Mechanical work (transfer of energy) is done when applying a force over a certain distance. Don't confuse force and energy (or force and work).
What is done when force makes an object move?
When a force makes an object move, work is done.
