constant velocity is when you maintain speed and direction, this usually is in a straight line, and constant speed means that your speed is always constant at all times.
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.
If constant motion means constant velocity then, total distance / total time = avg velocity => avg speed constant velocity => avg velocity = velocity
If the direction of motion is constant then the velocity is the same as the speed in that direction. If the direction is not constant, the information given is nowhere near sufficient to calculate the velocity.
No. Acceleration is the change in velocity(speed) over a period time.=====================================Another contributor bristled:Sorry. Velocity and speed are not two different words for the same thing.Velocity means speed and direction, and acceleration means any change in velocity.If the speed is constant but the direction is changing ... like turning a corner or drivingon a circular track ... then velocity is changing, and there is acceleration.
V = constant Speed = constant Direction = constant Acceleration = 0
Uniform velocity means that an object is moving in a straight line at a constant speed, while constant velocity adds the additional condition of moving with a constant speed and direction. In other words, constant velocity implies both uniform speed and no change in direction.
No, an object cannot have constant velocity and variable speed. Velocity is a vector quantity that includes both speed and direction. If the object's velocity is constant, then its speed must also be constant.
Yes, speed is the scalar of velocity.
No. Velocity includes a direction vector, which speed does not have.
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.
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.
This is not always the case. But if an object moves in a circle, at constant speed, its velocity will change. Velocity is a vector - consisting of the magnitude (the speed), and a direction. So by definition, if the direction changes, the velocity changes - you have a different vector.
No. It is a matter of definition. Acceleration is defined as a change of velocity. Technically, one must distinguish between velocity and speed. Velocity is a vector and includes the information about the magnitude (speed)and direction. One can have a constant speed and an acceleration (as in circular motion) but, by definition, constant velocity means zero acceleration.
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
No, if the instantaneous velocity of an object remains constant, then its instantaneous speed cannot change. Velocity is a vector quantity that includes both speed and direction. If the velocity is constant, it means both the speed and direction are 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.
Velocity is a vector quantity that includes both speed and direction. If the velocity is changing, it means either the speed, direction, or both are changing. Therefore, if the velocity is changing, the object cannot maintain a constant speed.
