Question

An object moves on a semicircle path calculate the ratio of distance and displacement

Answer 1

If an object goes from point A to point B on a semi circular path, then the distance covered will be the length of the arc and the displacement will be the diameter.
$\frac{ \frac{\pi \times r \times x}{180} }{2r}$
Where r = distance between A and B
and x = angle made by the semi-circle which is 180 degrees.
$\frac{\pi \times r \times x}{360r}$
$\frac{\pi \times x}{360}$
$\frac{\pi \times 180}{360}$
$\frac{\pi}{2}$
Thank you :) <3

Answer 2

Answer:

Step-by-step explanation:

As the magnitude of displacement always either less than or equal to distance travel. Hence, the numerical ratio of displacement to distance is either less than or equal to 1.
