Electricity magnetism electrostatics.
Work energy theorem in electrostatics.
M is the mass of the object measured using kilograms.
The amount of energy transferred by a force is called the work done by that force.
The work energy theorem can be derived from newton s second law.
Work is the product of force and displacement in physics a force is said to do work if when acting there is a movement of the point of application in the direction of the force.
Not like in the groovy sense.
Where w is the work done by object measured using joules.
Electricity magnetism electromagnetism.
Not that place you go to earn money.
In this live gr 12 physical sciences show we take a look at the work energy theorem.
W refers to the work done by the force f.
Physical sciences grade 12.
Also here the work done is the work done by all forces acting on the body like gravity friction external force etc.
V i is the initial velocity of an object measured using m s.
Where w g work done by gravity.
It states that the work done by all external forces is converted into a change of kinetic energy.
In order to transfer energy to an object you ve got to exert a force on that object.
In more general systems than the particle system mentioned here work can change the potential energy of a mechanical device the heat energy in a thermal system or the electrical energy in an electrical.
The video introduces the work energy theorem provides the definition of the work energy theorem and provides the work energy theorem formula.
For example when a ball is held above the ground and then dropped the work done on the ball as it falls is equal to the weight of the ball a force multiplied by the distance to the ground a displacement.
Thus the work energy theorem states that.
W g w n w f k f k i.
It turns out that kinetic energy and the amount of work done in the system are strictly correlated and their relation can be described by the work energy theorem.
W δke ke ke.
Actually energy is on.
V f is the final velocity of an object measured using m s.
W n work done by a normal.
Work transfers energy from one place to another or one form to another.
In physics it means something else.
