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).
What else can I help you with?
Work is done when a force is applied to an object if the object?
is moved
How much work is done when a vertical force acts on an object moving horizontally?
as work done is dot product of force and displacement so cos(90)=0;therfore work done is zero
Where did Charles Darwin get most of his evidence of evolution?
Observation of finches on the Galapagos Islands.
How do you calculate work done on an object .?
The equation to calculate the work done is: Work done (J) = force applied (n) x distance moved of force (m)
What happens when a force moves an object over a distance?
Work
What is required in order to determine whether or not object moves?
To determine whether an object moves, you need to observe its change in position over time. This can be done by comparing the object's initial and final locations. Additionally, measuring the object's displacement or calculating its velocity can also help in determining if the object is in motion.
What evidence is needed to prove work is not being done?
an object moves
When you perform work on an object you increase the energy of the object.?
Generally yes, but it really depends on the specific situation. -- If the work is done to lift the object, then the object's potential energy is increased. -- If the work is done to accelerate the object, then the object's kinetic energy is increased. -- If the work is done to move the object against friction, then the energy supplied is dissipated, and the object's energy may or may not change, depending on whether or not it is somewhat heated by the dissipation.
True or false work is done only when an object moves in the direction of the applied force?
False. Work is done whenever a force is applied to an object and there is a displacement in the direction of the applied force, whether the object moves in that direction or not. In cases where the object does not move, work is still done as long as there is a force applied over a distance.
What determines whether or not work is being done?
Work is done when a force is applied to an object and it causes the object to move in the direction of the force. Mathematically, work is calculated as the force applied multiplied by the distance the object moved in the direction of the force. If there is no movement or if the force is not in the same direction as the movement, then no work is being done.
When you perform work on an object do you increase the energy of the object?

What is required in order to determine whether or not an object moves?
To determine whether or not an object moves, you need to observe its change in position over time. This can be done by measuring its displacement or distance traveled relative to a reference point. By tracking the object's position at different time intervals, you can determine if it is in motion or at rest.
What evidence proves that NO work is being done on an object?
The only sure way to establish that would be to measure anddemonstrate that the sum of the object's(potential energy) + (kinetic energy) + (internal heat energy)is not changing.
What are some common types of problems that can be solved using the work-energy theorem?
The work-energy theorem can be used to solve problems involving the motion of objects, such as calculating the speed or height of an object, determining the force required to move an object, or finding the work done by a force on an object.
When can you say that work is done on an object?
when a force acts to move an object,we say that work was done on the object
What does it mean to object in a legal context?
To object in a legal context means to formally express disagreement or opposition to something being said or done during a legal proceeding, such as a trial or hearing. This is typically done to challenge the admissibility of evidence, question the relevance of a statement, or raise a procedural issue.
Where do you say that work is done an object?
Work is done on an object when a force is applied to the object and the object moves in the direction of the force. The work done is calculated as the product of the force applied and the distance the object moves in the direction of the force.
