What else can I help you with?
How can velocity change without changing the speed?
Consider velocity as consisting of a speed, and a direction. If any of the two changes - that is, if either the speed or the direction changes - then the velocity changes.
Can a change in velocity always indicate a change in speed?
Velocity has direction as well as magnitude. Speed only has magnitude. So the velocity of something can change without its speed changing. This is what is happening when something is going in a circle.
Which characteristic of motion could change without changing the velocity?
Well, we know that velocity describes the speed and direction of motion, so you can't change either of those. We don't usually think of 'position' as a characteristic of motion, but if we try hard to please you, then we might observe that the position changes while velocity remains constant.
When do speed and velocity become equal?
Speed and velocity become equal when an object is moving in a straight line without changing direction or when it is moving at a constant speed. Velocity is a vector quantity that includes both speed and direction, so if the direction of motion is constant, speed and velocity will be the same.
Why can velocity be negative but nonzero speed is always positive?
Velocity includes both speed and direction, so a negative velocity indicates motion in the opposite direction. Speed, on the other hand, is a scalar quantity representing the magnitude of velocity without regard to direction, and therefore is always positive.

Can the velocity of a body be constant still varying its speed?
Yes. Velocity is rate (or speed) in a given direction. If you change your direction but not your rate (or speed) then you have changed your velocity without changing speed.

Diffetiate speed and velocity?
Speed is a scalar quantity that represents the rate at which an object is moving, while velocity is a vector quantity that includes both the speed and the direction of motion. Speed is the magnitude of velocity without considering direction.
What factors could affect the velocity of a moving object but not the speed?
None, velocity is the speed at which something moves, they are the same thing
Can your speed and velocity ever have the same magnitude?
Speed and velocity always have the same magnitude, becausespeed is the magnitude of velocity.The difference is that velocity has a direction but speed doesn't
When is speed equal to the magnitude of velocity?
Speed is equal to the magnitude of velocity when the object is moving in a straight line without changing direction. In other words, if the velocity vector is pointing in the same direction as the motion of the object, then the speed will be equal to the magnitude of the velocity.
Which is vector speed or velocity?
"Speed" is a scalar; "velocity" is a vector.
Can a body have a constant velocity but varying speed?
No. If the speed varies, the body accelerates, and velocity cannot be constant.
