What else can I help you with?
What are science controls?
In an experiment, the control is the group to which nothing is done. It serves as a baseline to measure any changes that might occur to the group or groups that to which external variable is applied.
Work is done when a force is applied to an object if the object?
is moved
If you push on a box but the box moves backward you have done work?
Yes.
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 the unit of measurement for effort?
The unit of measurement for effort is the Newton (N). The effort applied to get work done can be equated to force applied.
Work is done when only what is applied?
Work is done when a force is applied to an object and the object moves in the direction of the force. It is calculated by multiplying the force applied by the distance the object moves in the direction of the force. If there is no movement, then no work is done.
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.
What is the only condition that work is done?
Work is done when a force is applied to an object and the object moves in the direction of the force. If there is no movement, no work is done, even if a force is applied.
Do all forces of an object cause work to be done?
No, work is only done by a force when there is displacement in the direction of the force. Forces that do not cause any displacement, such as static friction or normal force, do not do work on an object.
What is something done when a force moves an object over a distance?
Work is something that is done when a force moves an object over a distance.
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.
When an object moves work has occurred true or false?
True. Work is done when an object moves in the direction of the force applied to it. Work is calculated as the force applied multiplied by the distance the object moves in the direction of the force.
What two things need to happen for there to be work done on an object?
If he object moves as a force is applied and the direction of the objects motion is the same as the direction of the same force.
How do we know if work is 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. The work done is equal to the force applied multiplied by the distance the object moves in the direction of the force. If there is no movement or the force is not in the direction of movement, then no work is done.
What has to happen in order for work to be done on an object?
Work is done on an object when a force is applied to move the object through a distance in the direction of the force. The amount of work done is equal to the force applied times the distance the object moves.
What is needed for work to be done on an object?
Work is done on an object when a force is applied to it and the object moves in the direction of the force. The amount of work done is calculated as the product of the force applied and the distance the object moves in the direction of the force.
