The educational resource shows an interactive animation about the second law of thermodynamics for heat engines: it is not possible to achieve perpetual motion based on continuous reciprocal conversio ...
The forces of friction, which oppose displacement, also carry out work when a body is moving. The work of friction is converted into heat. The greater the force of friction, the more force must be exe ...
The area of the graph between the curve F and the X axis, represents the work carried out by the force between the two positions x0 and x. Review how to use the following visual and carry out the two ...
The educational resource shows a visual about the relation between field intensity and potential: the work carried out by the field when a charged particle q moves from one point to another, only depe ...
Work is one of the ways of transmitting energy between bodies. The following visual will help you understand the concept of work by modifying the force and the angle which it forms with the horizontal ...
The following visual studies the work done by a pendulum: it is difficult to calculate as the force which acts on it varies constantly. If you select Table and start the animation you will be able to ...
Power measures the speed with which work is done. It is measured in watts, W, in the International System of Units. The following visual will help you to understand this concept more clearly as you se ...
When we stretch a spring, the work we carry out varies as we stretch it because the force we have to exert at every instant is constantly varied. The force which has to be exerted must compensate for ...
Forces can carry out work. The work done by a force is different if it has the same direction and orientation as the displacement, or if its direction is different. Verify it in the following visual.
The educational resource shows a visual about the work: the word work has a very different meaning in Physics from the one we use in daily life. In daily life, work is equivalent to "effort"; in Physi ...
