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
velocity = distance / time There are also some formulae involving acceleration; for example, in the case of constant acceleration: velocity = initial velocity + acceleration x time If the acceleration is not constant, an integral is used instead.
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.
constant velocity means the speed and direction are the same.
An object moving in a straight line at a speed of 50 km/h with a constant velocity of 50 km/h in the same direction is an example of constant speed and constant velocity.
constant
Velocity magnitude is unchanging at constant speed. The direction might change (velocity is a vector with both size (speed) and direction) if , for example, you are driving around a curve at a constant speed.
No, acceleration refers to a change in speed or direction. If something is moving with a constant speed, it is not accelerating.
An example of constant speed with changing velocity is a car moving in a circular path. The speed of the car remains constant, but the velocity changes because the direction of the car is constantly changing as it moves around the curve.
Of course. In fact, in order to have constant velocity, it must have constant speed.What you really want to know: Can a body have changing velocity when it has constant speed ?The answer to that one is also "yes", for example when it is moving in a circle, the speed is constant but the velocity is changing all the time (in direction).
rotational motion
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.
No, if an object has constant speed, its velocity must also be constant. Velocity is a vector quantity that includes both speed and direction. If the speed is constant, the direction must also be constant for the velocity to be constant.
Constant means that something doesn't change; "changing" means that it does. Speed is a magnitude - measured (for example) in meters per second. Velocity, on the other hand, is a vector - which means that the direction is also considered. If an object changes direction - for example, moving in a circle - it is possible to do so at a constant speed. However, since the direction changes, the velocity will - by definition - change.
Yes, speed is the scalar of velocity.
