A block is placed on the horizontal surface. There are two forces acting on the block. One, the downward pull of gravity and other a normal force acting on it. Are these forces equal and opposite? Do they form action - reaction pair? Discuss with your friends.

When two equal and opposite forces acting on the body at two different points, it may give

A block of mass m_1 is pulled along a horizontal frictionless surface by a rope of mass m_2 . If a force F is given at its free end. The net force acting on the block is

A block placed on a rough horizontal surface is pulled by a horizontal force F. Let f be the force applied by the rough surface on the block. Plot a graph of f versus F.

If a 5N and a 15 N forces are acting opposite to one another . Find the resultant force and the direction of action of the resultant force

A block of mass M is kept on as rough horizontal surface. The coefficient of static frictionbetween the block and the surface is mu . The block is to be pulled by applying a force to it. What minimum force is needed to slide the block? In which direction should this force act?

A block of mass m is kept on a horizontal table. If the static friction coefficient is mu ., find the frictional force acting on the block.
