Work energy theorem integral.
Work energy theorem for variable force.
The work done on an object is equal to the change in its kinetic energy.
Thus we can say that the work done on an object is equal to the change in the kinetic energy of the object.
Kinetic energy and the work energy theorem.
Deriving the work energy formula for variable force is a bit hectic.
Review the key concepts equations and skills for the work energy theorem.
If the force varies e g.
A constant force is rare in the everyday world.
Compressing a spring we need to use calculus to find the work done.
In physics it means something else.
A variable force is what we encounter in our daily life.
Understand how the work energy theorem only applies to the net work not the work done by a single source.
This is the derivation of work energy theorem.
General derivation of the work energy theorem for a particle.
We have a neat trick that allows us to relate the change of the speed to the net force.
Work of a force is the line integral of its scalar tangential component along the path of its application point.
Not that place you go to earn money.
The force that we come across everyday is usually variable forces.
Actually energy is on.
Proving the work energy theorem for a variable force is a little tricky.
If and are the the starting and ending positions and are the the starting and ending velocities and is the force acting on the object for any given position then.
Therefore we have proved the work energy theorem.
Work energy theorem suppose that an object of mass is moving along a straight line.
The net force is proportional to the time derivative of the velocity vector and we can use the product rule for derivatives of dot products of vectors so let s take a derivative of the square of the velocity.
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.
