Define erg and define magnitude of force
Answers
magnitude of force:
The 'magnitude' of a force is its 'size' or 'strength', regardless of the direction in which it acts. For example, the force of a 5-pound weight in your hand, pushing down, has the same magnitude as a 5-pound pull on a rope, a 5-pound push on a wall, or a 5-pound force pushing up against the ceiling. Technically, these forces are unequal, because they all have different directions. But their magnitudes are all the same.
erg:
a unit of work or energy, equal to the work done by a force of one dyne when its point of application moves one centimetre in the direction of action of the force.

Answer:
erg
a unit of work or energy, equal to the work done by a force of one dyne when its point of application moves one centimetre in the direction of action of the force.
Magnitude of force
. The magnitude of the net force acting on an object is equal to the mass of the object multiplied by the acceleration of the object.
