Question

What is called uniform velocity? State the condition necessary for motion with constant velocity

Answer 1

$<marquee>hey friend you don't worry$

during uniform motion of an object along a straight line velocity remains constant with
time

hear the change in velocity of an object of any time interval is zero

acceleration is positive if it is in the direction of velocity

Answer 2

Hey dear,

◆ Uniform velocity -
- A body is said to have uniform velocity if it covers equal distance in equal intervals of time in a particular direction. i.e. s/t = constant.

◆ Conditions for Constant velocity -
1. A body moving along straight path with constant speed is said to have constant velocity. i.e. dv = 0.
2. As velocity is constant, acceleration also must be zero. i.e. a = dv/dt = 0 .
3. As acceleration is zero, net force acting on the body also becomes zero. i.e. F = ma = 0 .

Hope this helps you...
