Part A: Multiple TRUE/FALSE
1. Which of the following statements about vectors and scalars are TRUE? List all that apply.
- A vector is a large quantity and a scalar is a small quantity.
- A scalar quantity has a magnitude and a vector quantity does not.
- A vector quantity is described with a direction and a scalar is not.
-Scalar quantities are path dependent quantities and vector quantities are not.
- A scalar quantity depends only upon the initial and final values of the quantity; this is not the case for vector quantities.
- The quantity 20 m/s, north is a speed and as such is a scalar quantity.
- The quantity 9.8 m/s/s is an acceleration value and as such is a vector quantity.

Hope this helps!!

A vector quantity is described with a direction and a scalar is not.

Scalar quantities are path-dependent quantities and vector quantities are not.

Explanation:

Scalar quantity:

  • It is a physical quantity that only has magnitude.
  • It is a 1-dimensional
  • Its changes when magnitude changes.
  • It can't be resolved.
  • It is a path-dependent quantity.
  • If any mathematical operation is applied between two or more scalar quantities will give a scalar.
  • For example: mass, time, energy, etc

Vector quantity

  • It is a physical quantity that has magnitude and direction.
  • It can be the 1-dimensional,2-dimensional, or 3-dimensional
  • Any change in it changes its direction or magnitude or both.
  • It can be resolved.
  • It only depends on the initial and final values of quantities.
  • If any mathematical operation is applied between two or more vector quantities will give a scalar or vector.
  • For example: force, velocity, pressure, etc.

So from this, we can conclude that the true statements out given statements in the question are:

A vector quantity is described with a direction and a scalar is not.

Scalar quantities are path-dependent quantities and vector quantities are not.
