Limitations of work energy theorem?
it doesn't define direction of velocity
If work done on an object is equal to object's change in kinetic energy this the state of?
the Work-Energy Theorem states the work done is equal to the change in kinetic energy.
According to the work-energy theorem in the absence of friction if you do 100 J of work on a cart you'll increase its kinetic energy by?
100J
What is the importance of work-energy theorem?
it is a modified version of one of the newtons equation , newton equation cannot define the relation between work and enrgy thats why we generate the relation for work enrgy theorem
Does the work energy theorem hold if friction acts on an object?
Yes, some work is converted into heat due to the friction.
What if energy was not conserved?
Then, according to Noether's Theorem, the laws of nature would change over time. (Nowadays the Law of Conservation of Energy is commonly derived from Noether's Theorem, but it was known for a long time, from experience, that energy was conserved.)
Pythagoras theorem will always work in what type of triangle?
Pythagoras theorem will always work with a right-angled triangle.
Why doesnt energy disappear?
It has been found by experience that energy is conserved. Currently, the conservation of energy is derived from Noether's Theorem, but that is some very advanced math.It has been found by experience that energy is conserved.

Does hexagon work on Pythagoras Theorem?
no
How can the work-kinetic energy theorem explain why the force of sliding friction reduces the kinetic energy of a particle?
Work = change in Kinetic Energy Because friction acts in the opposite direction of the motion of an object, kinetic energy must be decreased in order to maintain the above equation. Friction opposes motion. Friction converts the kinetic energy of a particle into heat and sound.
What does negative response in superposition theorem implies?
work
Does the Pythagorean theorem always work?
No it never works.
