Concurrent force is a term used to describe forces that:
act at the same point
act in the same direction
have the same magnitude
occur at the same time
Explain what is meant by 'non-concurrent force'.
A force that acts at a single point
A force that does not act at a single point
A force that is always in equilibrium
A force that acts in a circular motion
Explain what is meant by 'coplanar force'.
A force that acts in three dimensions
A force that acts in a single plane
A force that acts in a vacuum
A force that acts in a circular motion
'Non-contact force' is a force that:
acts only when objects are in physical contact
acts at a distance without physical contact
requires a medium to travel through
is always attractive in nature
