Question

1.Give three examples of vector and their counter parts?
2.Difference between scalar and vectors

Answer 1

1. Examples of vectors and their counterparts:

a) Vector: Displacement vector (magnitude and direction)
Counterpart: Distance (only magnitude)

b) Vector: Velocity vector (magnitude and direction)
Counterpart: Speed (only magnitude)

c) Vector: Magnetic field vector (magnitude and direction)
Counterpart: Magnetic field strength (only magnitude)

2. Difference between scalars and vectors:

Scalars:

- Scalars represent quantities that have only magnitude but no direction.
- Examples of scalars include distance, speed, mass, temperature, time, and energy.
- Scalars can be added, subtracted, multiplied, and divided using ordinary arithmetic procedures.
- Scalar quantities are independent of any frame of reference.

Vectors:

- Vectors represent quantities that have both magnitude and direction.
- Examples of vectors include displacement, velocity, force, acceleration, and electric field.
- Vectors follow specific rules of vector addition and subtraction, taking both magnitude and direction into account.
- Vector quantities are dependent on a specific frame of reference for accurate representation.
