What is the motion of an object said to be if its velocity is constant?
the object is on uniform motion
Is the velocity constant for an object in uniform circular and why?
The velocity of an object in uniform circular motion is constant, because, velocity is the rate of change of position at a given time or speed.
Why an object at rest can be considered to have uniform motion?
An object at rest has constant velocity of zero, thus still uniform motion.
What is a motion with a constant velocity?
It is called uniform motion because the object covers equal distances in equal intervals of time which is why it has a constant velocity.
What are the conditions for an object to stay at rest to keep moving at constant velocity or to move with increasing velocity?
If the sum of all forces on an object is zero, then the object remains in constant, uniform motion. 'Constant uniform motion' means motion in a straight line at a constant speed. The physical description of such motion is "constant velocity". "Rest" is just constant velocity with a speed of zero. If the sum of all forces on an object is NOT zero, then the object's velocity must change. The change may consist of speeding up, slowing down, or turning in a different direction.

What accelerates while traveling at constant velocity?
An object in uniform circular motion undergoes constant acceleration but moves at constant "speed".Constant "velocity" means no acceleration.

If the sum of the forces is in the same direction as the object's motion, then the object must speed up.
What is the Distinguish between uniform and non uniform motion?
In uniform motion, the velocity of the object is constant: both in magnitude and in direction. In non-uniform one or other (or both) of these will vary.
Does velocity of an object remain constant in uniform circular motion?
Velocity is a vector with magnitude (speed) and direction. Since the linear velocity changes direction the speed is constant but the velocity is NOT constant.
What are the conditions for an object to state at rest?
If the sum of all forces on an object is zero, then the object remains in constant, uniform motion. 'Constant uniform motion' means motion in a straight line at a constant speed. "Rest" is just constant uniform motion with a speed of zero.
Can an object have constant speed but variable velocity?
I think a body in uniform circular motion can have a constant speed, but variable velocity. Since this body is in circular motion, it changes it's direction. Thus having a variable velocity.
What are decondition for an object to stay addresto keep moving constant velocity or remove constant velocity?
If the sum of all forces on an object is zero, then the object remains in constant, uniform motion. 'Constant uniform motion' means motion in a straight line at a constant speed. The physical description of such motion is "constant velocity". "Rest" is just constant velocity with a speed of zero. If the sum of all forces on an object is NOT zero, then the object's velocity must change. The change may consist of speeding up, slowing down, or turning in a different direction. Note: If you can, you should try and find the question in writing, so you can see what it's really asking.
When is an object said to have uniform velocity?
It isn't. Constant velocity? Uniform velocity across a group of objects?
What is uniform acceleration in physics?
Uniform, or constant, acceleration is a type of motion in which the velocity of an object changes equal amounts in equal time periods.
What happens when no force acts on an object?
Nothing changes. When no force acts on an object moving with constant velocity, the body continues its motion with uniform velocity, or if the object is at rest, it will remain at rest.
What is difference between an object moving with uniform acceleration and an object moving with a constant velocity?
If there is acceleration (uniform or otherwise, but non-zero acceleration), the velocity changes. Constant velocity means that the velocity does not change.
What two quantities is necessary for uniform circular motion?
The only thing required for an object to show uniform circular motion is a constant centripetal force. The object will have constant speed and kinetic energy, but its velocity, acceleration, momentum, and displacement will change continuously.
What is uniform in uniform circular motion?
The speed of the object in motion, the radius of the curve in which it moves, the force acting on it to keep it moving in a circle, its angular velocity, and its centripetal acceleration, are all constant. Notice that its linear velocity is not constant, because the direction of its motion is always changing. Although I guess you'd have to say that its velocity is constant in polar coordinates, because the radial and tangential components are constant.
Uniform linear motion and uniform circular motion?
Linear motion (also called rectillinear motion) is motion along a straight line. Uniform linear motion ,which constant velocity is zero. when a body (or an object) moves in a circle , it is called circular motion. Motion in a circle is circular motion.
