We can do a quick units check to see that pressure force. This is because the magnetic force is always perpendicular to the direction of displacement so d W F. For a gas, work is the product of the pressure p and the volume V during a change of volume. Question 1 How much work is done by a force of 10 N in moving an object through a distance of 1 m in the direction of the force? 1 Answer Sorted by: -1 Magnetic forces do not do any work as per F q v × B, irrespective of the nature of the magnetic field.
What is the work done by the force of gravity on the object? The initial and the final points of the path of the object lie on the same horizontal line. Reason out whether or not work is done in the light of your understanding of the term ‘work’.Īn object thrown at a certain angle to the ground moves in a curved path and falls back to the ground. To start, its important to first be able to identify both the direction the object is. Calculate the work done by him on the luggage. 1.Find the direction of the force vector and the direction of motion. The formula used by this calculator to determine the time taken to do work with. 11.2).Ī porter lifts a luggage of 15 kg from the ground and puts it on his head 1.5 m above the ground. from the total energy transferred or work done and the power output. The object is displaced throughIJ m in the direction of the force (Fig. Work is a measure of the energy transferred to an object, as such it can be measured in. How much work is done in ploughing the length of the field?Ī force of 5 N is acting on an object. Write an expression for the work done when a force is acting on an object in the direction of its displacementĪ pair of bullocks exerts a force of 140 N on a plough.
Let us take it that the force acts on the object through the displacement. The displacement is, say 8 m, in the direction of the force (Fig.
