No. Since the object's direction changes all the time, it follows that its velocity is not constant. Its speed, on the other hand, may or may not be constant.

0The magnitude of the velocity will be constant however the direction will be constantly changing. The acceleration will remain constant towards the centre of the circle

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.

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.

No. Speed can remain constant when velocity changes, but velocity can't remain constant when speed changes.

In space, constant velocity equals constant movement, so if something doesn't have velocity it stays in place.

Yes. That means the velocity changes all the time. The speed may remain constant (in the case of a circular orbit), but the velocity (which includes the direction) changes.

Reading the question carefully, I can state categorically, withoutthe slightest fear of contradiction, that YES, the object's velocityremains constant when its velocity does not change.

the question is very simple.no a body does not have acceleration when it is moving with constant velocity ,because a body posses acceleration when its velocity is not remain conserved or constant.yes if a body have constant speed it may have acceleration but not in case of constant velocity.

No, the definition of acceleration is the increase change in velocity over time. An acceleration can also be a decrease in velocity over time. Constant velocity refers to an object that maintains the same velocity as time progresses. If the object has an acceleration, its velocity will not remain constant. In the case of rotational velocity there is a constant internal acceleration that has the magnitude v2/r

Velocity is a vector quantity in which both magnitude and direction must be taken into consideration. For an object to have constant velocity, it is necessary that both the magnitude and the direction of the velocity must be constant. Even if either magnitude or direction is variable, velocity will not remain constant. On the other hand, speed remains constant if direction is changed and magnitude is kept constant, as speed is a scalar quantity.For an object to have constant velocity, it is necessary that the object move at a constant speed and not change course. That object must move in a straight line to have a constant velocity.

Since the velocity is constant due to the fact that there are no external forces acting in the horizontal direction, if you neglect air resistance, therefore, the horizontal velocity of a projectile is constant.

the horizontal component remain unchanged because there in no acceleration in horizontal direction

No. Acceleration IS a change of velocity - any change. When velocity increases, there IS acceleration. The acceleration itself may be increasing, decreasing, or remain constant.

-- horizontal velocity -- vertical acceleration

If the speed of the object doesn't change, then yes.

when a body changes its direction its velocity is changed though its speed may remain constant coz velocity is a vector quantity and speed is scalar.Being a vector quantity its value depends on direction and changes if the direction is changed though the speed remain constant.For example: when a body is in circular motion its velocity changes at every point as its direction is changes at every point.

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.

An object that is rotating at constant angular velocity will remain rotating unless it is acted upon by an external torque.

Newton's Law of Inertia states that an object in motion will remain in motion along a ___________ line, given a constant velocity and if no external force is applied.

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.

newton's first law states: an object will remain at rest or at a constant velocity unless the forces on it become unbalanced. As the forces on the object are now balanced it falls at a constant velocity. For falling objects this is called the terminal velocity

If the nominal interest rate is constant, then PY is constant in the equation PY = MV, so V will remain constant so long as money supply does not change.

If there are no outside forces acting on a system of particles the total momentum of the system will remain constant; i.e. the center of mass of the system will remain at rest or move at constant velocity.

Cart experiences a change in velocity(which is a vector quantity, not like speed). Cart's velocity on circular track has to be tangent to track at each point and because of that it has to change its direction. Speed may or not remain the same, you can't tell it changes in each possible case. Mass and weight remain the same.

ACC TO FORMULAE p=mv2 WHERE p=MOMENTUM, m=MASS, v=VELOCITY IF MASS REMAIN CONSTANT , THEN CHANGE IN MOMENTUM IS DUE TO CHANGE IN VELOCITY. THEREFORE MOMENTUM IS DIRECTLY PROPOTIONAL TO VELOCITY.
