Question

In the following physical quantities, identify the sclar and vector quantities. a) distance b) displacement c) speed d) velocity f) force g) mass h) time i) pressure j) density

Answer 1

a) vector.

b. vector

c scalar

d. vector

e. vector

f. vector

g. scalar

h. scalar.

I. scalar

j. scalar

Answer 2

Answer:

a,c,g,H, are scalar

Explanation:

1. scalar means the quantity has only magnitude but no specific direction
2. vector means having both magnitude and direction
3. by this we can calculate whether the given example is vector or scalar
4. force is a vector quantity because it has the direction of velocity by Newton's second law
5. pressure may have direction because it flows from low to high
6. I think density don't have direction but if you think clearly less dense particles flow on high dense particles this implies density has direction
