Question

identify the following as scalar or vector quantities: - mass,velocity,speed, length,distance,displacement,temprature,force,weight,work and energy

Answer 1

Sclar quantities-speed,mass,length,distance,temperature,work,weight,energy

Vector quantities-displacement,velocity,force

Answer 2

Answer:

Scalar terms are distance, speed, mass, energy, length, work, and temperature. Vector terms are weight, displacement, force and velocity.

Explanation:

• The quantities which have only magnitude, are called scalar quantities.
• Vector quantities are denoted by both magnitude and direction.

Step 1:

We observe that mass, speed, length, distance, temperature, work, and energy can be denoted by their magnitude only.

Step 2:

For, velocity, displacement, force, and weight we have to look for the directions also. For these quantities, magnitude and direction both are present.

So, scalar terms are distance, speed, mass, energy, length, work, and temperature.

Vector terms are weight, displacement, force and velocity.
