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
Do all forces of an object cause work to be done?
If a force is applied, but nothing in the system moves, no work has been done. Work is only done when something moves.
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.
When can use say that work is done?
Work is done when a force is applied to an object which moves in the direction of the force.
True or false work is done only when an object moves in the direction of the applied force?
true!
Is there work done when an asteroid moves in space with the absence of external force?
Work is equal to Force x Distance. If no force is applied, no work is done.
How much work is done if you hold a 50lbs box for 5 hours?
No work is being done. Work is when an object moves in the same direction as the force applied to it.
When a force is applied that moves an object in the direction of the applied force is gravity done?
Gravity is indeed a force, but only one out of many. magnetic, frictional, mechanical ... . When an ordinary force applied to an object, (me pushing my wheelbarrow) this would not be considered as being affected by gravity.
Work is done when?
work= force × distance so if an object moves 4metres, and the force to move it is 2N, (Newtons) the work done would be 4 × 2 = 8Joules (Work is measured in Joules) In other words, work is done when an object moves a certain distance when a certain amount of force is applied to it.
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.
When do you say that work is done?
work is only said to be done when force applied to a load moves through a distance.that is to say that a man standing one place carry a load without moving for 5 hours have not done any work.
What has been accomplished when a force moves and object over a distance in the same direction as the force is applied?
"Work" - in the mathematical sense - has been done; i.e. transfer of 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.
