Practise defining and calculating work with force and distance, then connect mechanical or electrical work to kinetic, gravitational and thermal energy transfers.
A mass is lifted from rest on the ground to Y. There is no air resistance.

P is the increase in gravitational energy of the mass.
Q is the kinetic energy of the mass at Y.
Which expression is equal to the mechanical work done on the mass?

Fig. 3.1 shows an archer aiming an arrow at a target.

Fig. 3.1
The archer pulls back on the bow string, doing a total of 110 J of work. Her hand moves a distance of 0.45 m . The bow is bent and stores energy.
Show that the average force applied by the archer in pulling the string back is approximately 240 N .
