Can work input be negative
WebSep 29, 2024 · Yes, work is negative if the displacement is in the opposite direction of the applied force. Is frictional force negative? A work done by friction is always negative. What is an example of negative work being done? When one jumps, then the work done by the gravitational force is negative work done. WebIf the answer in negative, then it has a "-" preceding a number. E.g -2,-35,-13,-34, are all negative numbers. Also remember this: - Positive/positive = positive - Negative/negative = positive - Negative/positive = negative - Positive/negative = negative hope that helps !

Can work input be negative
Did you know?
WebAug 29, 2024 · Yes work done is a scalar and it does not have a direction. But in a sense, it does have a scale to it. So it can be negative/positive. Example, the most common is temperature. It can have negative and positive values. A more common use of negatives in work done is also electrical potential energy/electrical work.

Since by the definition of work done,W= F.s = Fs cos (angle between f and s),thus whenever angle is >90, cos (angle) is negative and hence work done is negative.
WebNow in a previous video, we saw how to calculate work. It's calculated as force acting on an object multiplied by the displacement of that object. This means that to do work, in physics, you need to push or pull on something, and while pushing or pulling, you have to make it move. This is how we do work in physics.
