acceleration
No.. this is impossible. Velocity must have a constant direction and speed to remain constant, it may have a constant speed, but the direction in a circle constantly changes. If it suddenly were to have constant direction, then the motion would go off on a tangent.. making it linear motion, not circular. In circular motion, velocity constantly changes. Always.
No, the velocity of an object in uniform circular motion is not constant because although the speed may remain constant, the direction of the velocity continuously changes as the object moves along the circular path. This change in direction indicates a change in velocity, known as acceleration.
No. Velocity has direction and magnitude. The magnitude can be constant, but if the body is in circular motion, the direction of the movement is constantly changing, which means that the velocity is constantly changing. Changing velocity means that the body is accelerating. In this case, because the motion of the body is always changing away from a straight line to cause it to go round the circle, the acceleration acts towards the centre of the circle.
When a body is said to be in uniform motion, it means that it is moving in a straight line at a constant speed without changing its direction. There is no acceleration involved in uniform motion, making its velocity remain constant throughout.
this my sound rather daft but this is a bit of a trick question, the speed is the same so straight away you would think the acceleration is constant right....???? Wrong the displacement of the object is changing (displacement is the distance being travelled with a direction, a vector quantity.) as the displacement is changing so is the velocity, as velocity is displacement/time. as the velocity is changing so is the acceleration because acceleration is then change in velocity divided by time.

Newton's first law of motion tells me that I will remain in constant uniform motion unless I am acted on by an external force.

Motion with uniform velocity. * * * * * There is absolutely no reason for the velocity - or even speed - to remain constant. It is linear motion an that is all that there is to it.
Anything in circular motion is accelerated.'Acceleration' does NOT mean 'speeding up'. It means any change in the speedor the direction of motion.Circular motion involves constantly changing direction, and that's constant acceleration.
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.
The tendency of an object to remain at rest or in motion with a constant velocity is known as inertia.
If no force acts on an object, it will remain at rest if it was initially at rest, or continue moving at a constant velocity if it was already in motion. This is known as Newton's first law of motion, which states that an object will remain in its state of motion unless acted upon by an external force.
The "natural state" of an object is to be in constant, uniform motion ... moving in a straight line at a constant speed. In order for any object to leave that state, an external force must act on it.
