Question

Define speed ? Mention the formula for calculating it .

Answer 1

1. Speed is the distance covered by an object in a unit time .
2. The distance of an object covered in a given interval of time enables us to know whether an object is moving fast or slow.
3. Motion of an object can be measured in terms of speed .
4. It means slow-moving objects move at a slower speed and fast-moving objects move at a higher speed.
5. Speed of an object can be calculated by the below formula.
6. Speed (S) = $\frac{Dis\tan cetravelled\left(d\right)}{Time\hspace{0.17em}\left(t\right)}.$
7. The commonly used units of speed are kilometre per hour ($\frac{km}{h}$) and metre per second ($\frac{m}{s}$) .
