Question

The velocity is constant in a regular circular motion. True or false

Answer 1

Answer:

Velocity remains constant in a uniform circular motion whereas it varies in a non-uniform circular motion

please follow me

Answer 2

Answer:

$\red{\bold{False}}$

Explanation:

The velocity is constant in a regular circular motion is false .$\green{\bold{because}}$ Since the direction of motion keeps varying in a circular motion, velocity also keeps varying in a circular motion .

Additional information -

$\orange{\bold{Velocity \:}}$ is defined as distance travelled by it per unit time in a given direction .

⟹ $velocity \: = \frac{distance \: travelled \: in \: given \: direction \: }{time \: taken}$

In easy way -

⟹ ${v}^{⟶} = \frac{displacement}{time}$

$\red{\bold{Therefore, }}$

Velocity of the body is displacement produced per unit time .

⟹ $si \: unit = \frac{m}{s}$

$\red{\bold{Must\:Remember\:-}}$

• Velocity measures the rate of change in position that is change in position per unit time .
• Velocity is a vector quantity as it has magnitude as well as direction .
