Question

Work done by a force is given by the equation W = F cos ϴ  s. Determine and
explain the effect of work done due to a gradually increasing angle ‘ϴ’.

Answer 1

If angle ø is increased,then its value is decresed.(cos 0°>cos 30°c>cos 45°c>cos 60°c>cos 90°c).

So,if ø is increased in the equation

W = F(cos ø)

Then,the force will decreased.
