symbols of vector quantities. Vectors quantities are usually represented by boldface type. e.g. V in printed material. When written by hand, the designation is often used. representation of vector. A vector is a line drawn to represent a vector quantity in . direction, by its arrow head, and. magnitude, by its length. e.g. consider 2 vectors and,

A quantity whose both magnitude and direction is called vector quantity. For example: displacement, velocity, acceleration, force, momentum, etc. On the other hand, a quantity which only has magnitude is called as scalar quantity. For example, time, energy, mass, and temperature.

A Vector Quantity is one which has both . magnitude. and direction. Examples: displacement, acceleration, force. Vectors can be represented on a diagram by an arrow, where the vector is in the same direction as the quantity it is representing. Composition (addition) of two perpendicular vectors.

One of the most important vector quantities in physics is the force vector . F. Because a force is a vector, it obeys the laws of vector addition and subtraction. This implies s that if several forces are at work on some object, each pulling or pushing on the object from a different direction, then the net or resultant force can be determined ...

First, you should remember from your introductory physics course that many other physics quantities are derived from the position vector including displacement, velocity, acceleration, linear momentum, angular momentum, etc. Thus, the question of reference frames and transformation equations is extremely important in physics.

23.20. Identify:The total potential is the scalar sum of the individual potentials, but the net electric field is the vector sum of the two fields. Set Up:The net potential can only be zero if one charge is positive and the other is negative, since it is a scalar. The electric field can only be zero if the two fields point in opposite directions.
