Work and energy. The work W done by a constant force of magnitude F on a point that moves a displacement s in a straight line in the direction of the force is the product. For example, if a force of 10 newtons (F = 10 N) acts along a point that travels 2 metres (s = 2 m), then W = Fs = (10 N) (2 m) = 20 J.

Power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. Power is a scalar quantity.
4 Ιουν 2021 · Work, Power and Energy is a very important concept in physics. Work done by all the forces is equal to the change in kinetic energy. In physics, work is related to the amount of energy transferred in or from a system by a force. It is a scalar-valued quantity with SI units of Joule. Work can be represented in a number of ways.
Thermodynamic work is one of the principal processes by which a thermodynamic system can interact with its surroundings and exchange energy.
The principle of work and kinetic energy (also known as the work-energy theorem) states that the work done by the sum of all forces acting on a particle equals the change in the kinetic energy of the particle.
Work is a special name given to the (scalar) quantity =. where is work, is force on the object and is displacement. Since the dot product is a projection, the work is the component of the force in the direction of the displacement times the displacement.
Power, P, is the rate at which work is done or energy is consumed. The SI unit of power is Watt (W) which equals one Joule per second (J/s). **Problem: Show that power is the dot product of force and velocity.
