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.
What else can I help you with?
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.
Can a body moving with uniform speed have variable velocity?
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
What is the greates velocity a falling object can reach called?
The greatest velocity a falling object can reach is called terminal velocity. Terminal velocity occurs when the force of air resistance on the object matches the force of gravity pulling it down, resulting in a constant speed.
Is it possible to have a changing velocity and a constant speed?
Yes, the velocity of a constantly (or not constantly) accelerated object will vary. Velocity is distance per unit time with a vector. It's speed (distance per unit of time) in a given direction. Under constant acceleration, the velocity is changing at a constant rate. But the velocity is changing. It is varying. The object could be speeding up or it could be slowing down. Or it could be changing direction. Any of these change velocity. An object that is experiencing constant acceleration will have its velocity varying. Why wouldn't it have?
What describes both speed and direction?
Velocity describes both the speed and direction an object is moving.
Can an object have constant velocity and but variable speed?
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.
Can an object have a constant speed and velocity at the same time?
Yes. An object moving in a straight line at constant speed has constant velocity.
What happens to the velocity of an object even if the speed of an object remains constant?
Velocity can change even if speed is constant.
Can an object have a constant spped and velocity at the same time?
Velocity is a vector quantity. That means it has direction and magnitude. Speed is a scalar quantity, it only has magnitude. It is possible to have constant speed and constant velocity but it is also possible to have constant speed but changing velocity if the object is changing direction.
When the velocity of a moving object stays the same it has a what speed?
When the velocity of a moving object stays the same, it has a constant speed.
Can an object accelerates when its speed is constant?
No, if an object's speed is constant, then it is not accelerating. Acceleration is the rate of change of an object's velocity, which includes both speed and direction. If an object's speed is constant, it means there is no change in velocity and therefore no acceleration.
If the instantaneous velocity of an object remains constand can its instantaneous speed change?
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.
Why the speed of an object is constant while the velocity is not?
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.
Can an object have a varyong speed if its velocity is constant?
No, if an object's velocity is constant, then its speed must also be constant. Velocity is a vector quantity that accounts for both the magnitude (speed) and direction of motion, so if the velocity is constant, both speed and direction will remain the same.
Can object at constant speed can maintain constant velocity?
Yes, an object moving at a constant speed can maintain a constant velocity if it is moving in a straight line without changing its direction. Velocity is a vector quantity that includes both speed and direction, so as long as the direction does not change, the object's velocity will remain constant.
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.
Can an object have varying speed if its velocity is constant?
no
