Potential energy stored in a spring to a body from moving it from x1 to x2 distances is given by_____
For equilibrium the net moment acting on the body by various forces is zero, in any of the body in the space, as in the space it is acted by various forces, like gravity.
We use sometimes the measures to know the direction of moment in the calculations of the moments caused by the gravitational forces over the body above the ground level. Which one is right about it(consider the mentioned axis to be positive)?
Determine the magnitude of the force F = 300j parallel to the direction of AB?
Which statement is correct about the vector F in the showing the gravitational nature of the forces?
Air also resist the body in the motion. The maximum value of the frictional force is called _________
The coefficient of kinetic friction when a body is moving from a height above the ground level to a smaller height is ____________ than coefficient of static friction.
Free body diagrams doesn’t play any role in making the calculations on the conditions of the equilibrium of the body when there is the involvement of the potential energy.
The net forces of acting on the body needs to be zero. This is also applicable for the bodies having some potential energy. This means that the work done over it is saved in the form of potential energy.
Virtual Work done is saved in the form of potential energy. It is best given by ___________
Which of the following is correct for the forces which are considered in the potential energy calculations?
For the conditions of the equilibrium of the body, i.e. the rigid body only the external forces defines the equilibrium. And the support reactions only cancels out the rotation part of the body and thus the potential energy of the body is stored in it.
