What's Your Question?
Answer

force is the dynamic load { force= mass× acceleration} and it can act in any direction. load is a static load { F= mg} and it can act only in downward direction.

Answer

Load and force are interchangebly used for the same physical quantity. SI unit of load and the force is N. But Load is mostly used in engineering while force is often seen in physics textbooks. Load can be tensile or compressive. Load is not always related to the weight i.e. mg. It's not always downward. Load on a member may be in any direction. In mechanical engineering, we come across the member of a structure which may be spring loaded for example spring loaded valves. So it's wrong to say that load is always vertically downward direction. We can say force is something which causes or tends to cause some change in the state of a rigid object while load is something which changes or tends to change the shape of an object or load deforms or tries to deform an object.   

Answer

Force is the dynamic load (force= mass \(\times\) acceleration) and it can act in any direction.

The load is a static load ( force= mass x acceleration due to gravity i.e. f= mg) and it can act only in the downward direction.

Answer

Load is one type of specific Force that always acts downwards.
