The total work done on a particle is equal to the change in its kinetic energy. This is applicable
A body of mass $8\,kg$ is moved by a force $F = 3x\,N,$ where $x$ is the distance covered. Initial position is $x = 2\,m$ and the final position is $x = 10\,m$. The initial speed is $0.0\,m/s.$ The final speed is ........... $m/s$
In the figure, the ball $A$ is released from rest when the spring is at its natural (unstretched) length. For the block $B$ of mass $M$ to leave contact with the ground at some stage, the minimum mass of $A$ must be
State the importance of work energy theorem. Whether the work energy theorem is a scalar or a vector ?
The force constant of a wire is $k$ and that of another wire is $2k.$ When both the wires are stretched through same distance, then the work done
