Physics Question on Work-energy theorem
The Work-Energy theorem states that the change in
A
Kinetic energy of a particle is equal to the work done on it by the neat force
B
Kinetic energy of a particle is equal to the work done by one of forces acting on it
C
Potential energy of a particle is equal to the work done on it by the net force
D
Potential energy of a particle is equal to the work done by one of forces acting on it
Answer
Kinetic energy of a particle is equal to the work done on it by the neat force
Explanation
Solution
According to work-energy theorem, change in kinetic energy of a particle is equal to the work done on it by the net force.,
i.e. W=F⋅S=21mv2
