No. Velocity has two parts, speed and direction A constant velocity means that both the speed and the direction must be constant. So a constant velocity must have a constant speed.
Constant velocity has speed always constant along the direction with respect to time. Variable velocity changes its speed with respect to time. Constant velocity has zero acceleration. Variable velocity has non-zero acceleration . An object moving at a constant velocity maintains both the same speed and direction. An object moving at a variable velocity can be changing speed or direction of travel or both.
No. Velocity is speed and direction. If you change either variable, the velocity will no longer be constant.
I think a body in uniform circular motion can have a constant speed, but variable velocity. Since this body is in circular motion, it changes it's direction. Thus having a variable velocity.
Uniform circular motion. The speed is constant but the direction thus the velocity is variable.
Velocity is a vector. A vector has a magnitude and a direction. The scalar or magnitude portion of velocity is speed. Velocity is a constant only when both the speed and direction are not varying. Hence, when the speed is changing, the velocity cannot be a constant.
If you are traveling in a constant direction with constant speed there are no changes in velocity, so you are not accelerating.
No. Constant velocity implies a constant speed, AND a constant direction.No. Constant velocity implies a constant speed, AND a constant direction.No. Constant velocity implies a constant speed, AND a constant direction.No. Constant velocity implies a constant speed, AND a constant direction.
Speed is a scalar quantity while velocity is a vector quantity.It is possible that an object can have constant speed but if speed is constant while direction of motion is changing constantly then it means that body has variable velocity.An example of this phenomena is a body moving in a circle whose speed is constant but velocity is changing every instant due to change in direction at every instant.
Yes, speed is the scalar of velocity.
No, constant velocity implies constant speed. But velocity can change even when speed remains constant, since speed is a scalar quantity but velocity is a vector quantity.
No. Velocity includes a direction vector, which speed does not have.
