Question

Which of the following quantities are vectors? Select all that apply. a. Displacement b. Distance c. Velocity d. Speed e. Acceleration

Answer 1

Answer:

Distance is a scalar quantity.

Velocity is a vector quantity.

Acceleration is a vector quantity.

Speed is a scalar quantity.

Displacement is a scalar quantity

Answer 2

Answer:

a. Displacement- Vector quantity

b. Distance - Scalar quantity

c. Velocity -  Vector  quantity

d. Speed - Scalar quantity

e. Acceleration- Vector quantity

Therefore, the options (a), (c) and (e) are vector quantities.

Explanation:

• Vector quantities are those which has both magnitude as well as direction.

• Scalar quantities are those which have only magnitude but not direction.
• The ratio of two vector quantities will be given a scalar quantity.

• Displacement is the shortest distance between the two points. So it has magnitude as well as direction. Therefore, displacement is a vector quantity.
• Distance is a scalar quantity because it has only magnitude but not direction.
• Velocity is a vector quantity because it is defined as the rate of change of distance per unit time in a particular direction.
• Speed is a scalar quantity because it is rate of change of the distance travelled by a body.
• Acceleration is a vector quantity because it is rate of change of velocity. So, it considered change in both direction as well as magnitude of the velocity.
