Question

1. The actual length covered by the body
is called
1) Distance
2) Displacement

3) Both (1) & (2)
4) Neither (1) nor (2)​

Answer 1

$\Large{\underline{\underline{\bf{Answer:-}}}}$

1. Distance (✔)

${\underline{\underline{\bf{Distance:-}}}}$ The actual length covered by the moving body, irrespective of the direction.

⠀⠀⠀⠀⠀⠀⠀⠀⠀or

The total movement of an object without any regard to direction.

More To Know!

➠ Distance is a scalar quantity, which have magnitude only.

➠ Distance travelled by a body is always positive, it can't be zero or negative.

➠ Distance travelled by the body is either greater than or equal to the displacement.

${\underline{\underline{\bf{Displacement:-}}}}$ The shortest distance between the initial and final positions of the body.

⠀⠀⠀⠀⠀⠀⠀⠀⠀or

The change in its position in a particular direction, during a particular time period.

More To Know!

➠ Displacement is a vector quantity, which have both magnitude and direction.

➠ Displacement of a body may be positive or negative or zero.

➠ Displacement of a body is either less than or equal to the distance travelled.

Answer 2

Answer:

$\huge{\bf{\underline{\red{Answer :}}}}$

$\rm\underline\bold{1)\: Distance \red{\huge{\checkmark}}}$

2) Displacement

3) Both (1) & (2)

4) Neither (1) nor (2)

What is Distance:-

the extent or amount of space between two things, points, lines, etc.

Formula:-

$d =\Large\sqrt{x_2 - x_1)^2 + (y_2 - y_1)^2}$

$\Rightarrow$D = Distance

$\Rightarrow$$(x_1 , y_1)$ = coordinates of the first point.

$\Rightarrow$$(x_2 , y_2)$ = coordinates of the second point
