Question

Force has a magnitude as well as - a) interaction . B) measurement . C) value .D) Direction

Answer 1

Answer:

option D

Explanation:

as the force is vector quantity which has magnitude as well as direction

Answer 2

Answer:

Force has magnitude as well as :-

direction

Let us take a simple example to prove this statement:

Let the force be 2N (N= Newton)

Here, 2 is the magnitude or value of the force.

As there is no sign i.e. positive or negative sign, then automatically we assume a positive sign.

So, 2N= +2N

This positive sign denotes the direction of force. If he sign is positive(+), it means that the force applied is in the same direction of motion of the object. But, if the sign is negative(-), then the force applied is opposite to the direction of motion of the object.

⇒ 2N is a force of magnitude 2 and it is applied in the same direction of motion as that of the object.

⇒ -2N is a force of magnitude 2 but it is in the opposite direction of motion as that of the object.

Remember:- Frictional Force will always be denoted with a negative sign because friction always acts in the opposite direction of motion of the object.
