(a) Suppose a constant force acts on an object, The force does not vary with time or with the position or the velocity of the object. Start with the general definition for work done by a force:
and show that the force is conservative.
(b) As a special case, suppose the force acts on a particle that moves from O to c in Figure P7.43. Calculate the work done by F on the particle as it moves along each one of the three paths shown in the figure and shows that the work done along the three paths are identical.
A force where is in newtons and x and y are in meters. acts on an object as the object moves in in the x direction from the origin to x = 5.00 m. Find the work done by the force on the object.
A constant force F=(-2.8i+3.6k)N acts on an object with a mass of 13kg that moves from r1=(-2i+1.5j+6k)m to a new position r2=(-4j+3k)m. What is the work done by the force
