No. It can keep a constant SPEED in a curve. But if the direction changes, then
that's a change of velocity, and the direction in a curve is constantly changing.

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.
What path might an object take that involves changing its velocity?
Any path that changes direction. To keep the speed constant and change the velocity it would have to travel in a circle or something similar.
When you run around a track at 5 km h your velocity is constant?
No. Your speed is constant but your velocity is not. Velocity is a vector and as you run around a track, the direction of your motion changes and so the velocity changes - not in magnitude but in direction.
If a force is exerted on an object is it possible for that object to be moving with constant velocity?
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.
Do balanced forces cause motion?
No. An unbalanced force causes motion, but balanced forces keep a body in motion in a straight line at constant velocity, or at rest at constant 0 velocity.

What are the conditions for an object to stay at restto keep moving at constant velocity?
"Constant velocity" means neither the speed nor the direction of the object's motion is changing. "Rest" is just one kind of constant velocity ... the kind with zero speed. The condition for an object's velocity to remain constant is: Either there are no forces acting on the object, or else all of the forces acting on it add up to zero. If there is any NET force acting on the object, then its velocity will change ... it will either speed up, slow down, or curve in a new direction.

What are the conditions for an object to stay at rest to keep moving at constant velocity or the move with increasing velocity?
A body is moving at constant velocity including zero at Equilibrium Condition, No change of energy or zero force. With force a body can accelerate, move with increasing velocity.
Do balanced forces cause motion?
No. An unbalanced force causes motion, but balanced forces keep a body in motion in a straight line at constant velocity, or at rest at constant 0 velocity.
What are the condition for an object to keep moving at constant velocity?
No resultant forces act upon it
Before the 17th century what ideas did people have concerning motion velocity and acceleration?
There were many different ideas, but they all went something like this: Most people thought that the natural state of an object was at rest, and that force needed to be applied in order to keep an object moving at constant velocity. Of course, we now know that no force is needed for constant velocity, only acceleration.
What is a property of sound that changes with frequency?
If you change sound's frequency and hold the velocity constant, the sound's wavelength also changes. If you change sound's frequency and keep the wavelength constant, then velocity also changes.
What are the condtions for an object to stay at restto keep moving at constant velocity or to move with increasing velocity?
The Condition of Equilibrium, Force equal zero, is the condition of an object at rest or moving at constant velocity. Non-Equilibrium Condition, Force is not zero, is the condition for an object to move with increasing velocity.
What are conditions for an object to stay at rest to keep moving at constant velocity?
The condition for an object to stay at rest or if moving, moving at a constant velocity is that the sum of forces acting on the object be zero or that no force acts on the object.
