No. Speed is the magnitude of velocity. If the speed varies, so will the velocity, even if you are moving in a uniform direction.
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 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.
No. Velocity is speed and direction. If you change either variable, the velocity will no longer be constant.
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.
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.
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.
If you are traveling in a constant direction with constant speed there are no changes in velocity, so you are not accelerating.
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.
Yes. Acceleration is defined as a change in velocity, and velocity is a measure of speed AND direction. Maintaining a constant speed while rounding a corner is an example of acceleration.
No. Velocity includes a direction vector, which speed does not have.
If you are traveling at a constant speed with changing direction there is a change in velocity, so you are accelerating.
If you are traveling in a constant direction with changing speed there is a change in velocity, so you are accelerating.
Velocity is Speed in a given direction. Moving at constant velocity is equivalent to say moving with a constant speed in a specified direction. So, moving at constant velocity implicitly means moving with constant speed.
Velocity is a vector quantity in which both magnitude and direction must be taken into consideration. For an object to have constant velocity, it is necessary that both the magnitude and the direction of the velocity must be constant. Even if either magnitude or direction is variable, velocity will not remain constant. On the other hand, speed remains constant if direction is changed and magnitude is kept constant, as speed is a scalar quantity.For an object to have constant velocity, it is necessary that the object move at a constant speed and not change course. That object must move in a straight line to have a constant velocity.
Velocity consists of a speed and a direction. If any of the two changes, the velocity changes.
No. Speed is the magnitude of the velocity. If either or both the speed and direction vary, the velocity is not constant.
A changing velocity can maintain constant speed if the motion is circular. The constant change in direction is a change in velocity, even if the speed is constant.
Velocity is speed together with its direction.Acceleration indicates a change in velocity ... speed or direction or both.Change of direction means acceleration, even if speed is constant.Constant velocity means constant speed and direction ... zero acceleration.
Yes. Velocity includes the direction of the motion. If the direction changes, then that meansthe velocity changes, even if the speed is constant.Anything rotating at constant speed in a closed path has constantly-changing velocity.Like a point on a phonograph record, a point on a hard disk drive, or an orbiting TV satellite.
No. Circular motion can have constant speed but varying velocity. Constant speed means constant speed in any direction, like a car on cruise control turning a corner. Constant velocity means constant speed in a straight line. If the direction changes, that's considered a change in velocity.
No. Velocity combines speed and the direction of motion.Constant velocity is constant speed in a straight line.In circular motion, the velocity is always changing even if the speed is constant,because the direction is always changing.
Velocity is a quantity that has magnitude and direction. The magnitude of velocity is what we call "speed".If the velocity is constant, then its magnitude and direction are both constant.Constant magnitude means constant speed.So the answer to the question is "Yes".
