Is workdone is scalar or vector?
Work done is a scalar quantity. It is defined as the product of force and distance in the direction of the force, and does not have a direction associated with it.
What situations involves more power200 J of work in 20 s or 50 J of work done in 4 s?
Both situations have the same power output of 10 watts, as power is calculated as work done divided by time taken. In this case, 200 J of work done in 20 s and 50 J of work done in 4 s both result in a power output of 10 W.
Which of the situations involves more power200 Joules of work done in 20 seconds or 50 Joules of work done in 4 seconds?
The situation involving more power is 50 Joules of work done in 4 seconds because power is calculated as work divided by time. In this case, the power would be 12.5 Watts (50 J / 4 s = 12.5 W), while for the first situation it would be 10 Watts (200 J / 20 s = 10 W).
What do you mean by workdone?
Work done is the measure of energy transfer that occurs when a force causes an object to move a certain distance in the direction of the force. It is calculated as the product of the force applied and the distance moved in the direction of the force. Work done can lead to a change in the energy of an object.
When is workdone by force is zero?
Work done by a force is zero when the force is applied perpendicular to the direction of motion of the object. Another scenario is when the force is applied but there is no displacement of the object.
Why applying force to an object does not always result in work being done?
When a force (no matter how large it may be) is applied to any object without a distance being moved,it cannot be workdone because,workdone = force x distance.
Is there is any workdone in fan when it is rotating and consuming electricity?
The work is done when the fan moves air, imparting kinetic energy to the air.

How much work is done when a 48-kg stack of books are lifted 2m with a net force of 25 N?
Workdone =force * distance 25N * 2m = 50Nm OR 50joules
How is workdone equal to energy?
Work done on an object is equal to the energy transferred to the object to make it move or undergo a change in its state. This is based on the work-energy theorem, which states that the work done on an object is equal to the change in its kinetic energy. In other words, work done represents the transfer of energy from one form to another.
Why is the workdone by centripetal force is zero?
The work done by a centripetal force is zero because the force is always directed towards the center of the circular motion, while the displacement is perpendicular to the force. This means that the angle between the force and the displacement is 90 degrees, resulting in zero work being done.
How much workdone is done when a weight of 10n is raised 2m vertically?
The work done is calculated using the formula: Work = Force × Distance × cos(θ). In this case, the force is 10 N, the distance is 2 m, and the angle θ is 0 degrees since the force and distance are in the same direction. Therefore, the work done is 10 N × 2 m × cos(0°) = 20 Joules.
