When a force causes an object to move through a distance work is done on the object. |
|
What is happening when is work done on an object? |
|
|
|
A force does work on an object when the force causes a displacement of the object. |
|
When does a force do work on an object? |
|
|
|
One joule of work is done when a force of one newton causes a displacement of one metre.
1 joule = 1 newton-metre |
|
What is one joule of work done equal to? |
|
|
|
Students should be able to convert between newton-metres and joules |
|
How many joules are in 76 Nm? |
|
|
|
(MS) The work done by a force on an object can be calculated using the equation:
work done = force ? distance moved along the line of action of the force
W = F s
work done, W, in joules, J
force, F, in newtons, N
distance, s, in metres, m |
|
What equation is used to calculate work done by a force on an object? Include SI units. |
|
|
|
Students should be able to describe the energy transfer involved when work is done. |
|
What is the energy transfer that occurs when work is done? |
|
|
|
Work done against the frictional forces acting on an object causes a rise in
the temperature of the object. |
|
When work is done against the frictional forces acting on an object what happens to the temperature of the object? |
