Yes it can.When a body moves in a circular path keeping its speed uniform then it will have variable vilocity as vilocity is the speed in a particular direction and while moving in a circular path its direction keeps changing and so does vilocity

∙ 12y agoNo. "Velocity" means the speed and direction of motion.
If either of them is changing, then velocity isn't constant.
(By the way, that's what "acceleration" means: Any change in velocity.)
Wiki User
∙ 11y agoNo. Speed is the magnitude of velocity. If the speed varies, so will the velocity, even if you are moving in a uniform direction.

What describes both speed and direction?
Velocity describes both the speed and direction an object is moving.
When can an object a constant speed but not a constant velocity?
If the velocity is constant there is no acceleration. Speed is not velocity, velocity has speed and direction. I A car going around a circular track at 60 mph keeps the same speed but changes direction and thus accelerates at a constant speed. Velocity is speed in a certain direction. So change the speed but keep direction the same and you change the velocity. or Change the direction while keeping the speed the same and you change the velocity. If the speed is constant, any change of direction is a change in velocity. Driving around in a circle is a case of constantly changing direction.
Can an object moving at a constant speed have acceleration?
Acceleration is defined as the change in velocity over a given time period. Velocity is a vector quantity: it includes speed and direction. That being said, you can accelerate an object without changing its speed by simply changing its direction. A body moving along the circumference of a circle its speed may remain a constant, but its velocity will not be a constant since its direction of motion continuously changes, since the velocity changes it has an acceleration.
What 2 factors does the kinetic energy depend on?
It depends on mass and velocity. ans : it depends on the mass & speed of the moving object. no, it depends on the work & energy.
Is true that absolute value of speed equals velocity?
No, you've got it backwards. The absolute value of velocity equals speed. Velocity is speed with a direction; speed is just a number, without regard to direction.
What is the condition in which a body moving with uniform speed has a variable velocity?
Speed is considered a scalar while velocity is refered to as a vector. A vector can be varied with respect to its direction. Therefore, constant speed while changing direction varies the velocity
What is the nature of velocity time graph of a body moving with uniform retardation?
A body moving at a uniform speed may have a uniform velocity, or its velocity could be changing. How could that be? Let's look. The difference between speed and velocity is that velocity is speed.
What is the difference between constant velocity and variable velocity?
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.
What is difference between an object moving with uniform acceleration and an object moving with a constant velocity?
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.
What is the differnce between velocity and speed?
Velocity is a vector quantity. So direction is important But speed is a scalar. Body moving around a circle may go with uniform speed but not with uniform velocity as direction is changing continuously
If an object is moving at unifrom acceleration what is its velocity?
A body moving at a uniform speed may have a uniform velocity, or its velocity could be changing. How could that be? Let's look. The difference between speed and velocity is that velocity is speed with a direction vector associated with it. If a car is going from, say, Cheyenne, Wyoming to the Nebraska state line at a steady speed of 70 miles per hour, its velocity is 70 miles per hour east. Simple and easy. Uniform speed equals uniform velocity. (Yes, I-80 isn't perfectly straight there. Let's not split hairs.) But a car moving around a circular track at a uniform speed is constantly changing direction. Its speed is constant, but its velocity is changing every moment because the directionit is going is changing. Speed is uniform, but velocity isn't. As asked, uniform speed is a uniform distance per unit of time. And this will yield a uniform distance per unit of time in its velocity, but the direction vector may be uniform or it may be changing each moment, as illustrated.
What will be acceleration of a car moving in a circular motion with constant speed.?
If body is moving in a circle with uniform or constant speed its acceleration will be uniform as velocity i.e. to say direction is changing at every point.
What are two ways in which an object can have constant velocity uniform motion?
Objects moving in uniform circular motion will have a constant speed, and two objects with the same acceleration have a constant velocity.
Why the velocity and acceleration of body moving with uniform speed in circular path will be mutually perpendicular?
as direction is changing
Under what circumstances can an object moving with an constant speed (uniform magnitude oits velocity) have an acceleration?
When the direction changes. A simple case is an object moving in a circle, at constant speed.
When a body is moving with uniform velocity what is difference between distance and time?
the distance will be equal to the time multiplied by a factor which is the speed.
How the velocity uniform?
"Uniform velocity" means zero acceleration, that is, constant speed in a straight line.rate of change of velocity is zero
