Choose the correct statement

Options

A. Unit of acceleration is `ms ^(-2)`
B. Speed = distance/ time .
C. Magnitude of displacement made by a body is less than or equal to the distance travelled by the body.
D. All the above

Answer

D

Explanation

(1) The unit o acceleration is m ` s^(-2)`
(2) Speed = `("distance")/("time")`
(3)Displacement is the shortest distance between the initial and final positions in a specified diretion . So, the magnitude of displacement travelled by a body is less than or equal to the distance travelled by the body.
