a 10 g mass is whirled along a horizontal circular.what force maintains the motion along the circle?
It is constant in magnitude. It is changing in direction.
The force toward the centre of the circle is called the centripetal force. centrpetal acceleration.
In toward the center of the circle.
No! Carousels move in a circle (at least all the carousels I know do) in circular motion there is constant acceleration directed towards the center of the circle of magnitude a=v2/r
No. Velocity is a 'vector', which means it's a measurement that has both magnitude and direction. The magnitude is what we usually call the 'speed'. For an object moving in a circle, it could have constant speed ... the velocity could have constant magnitude ... but there's no way the whole velocity vector could be constant, because the direction is always changing. Constant velocity is very easy to recognize ... the object is moving at a steady speed, in a straight line.
It is constant in magnitude. It is changing in direction.
An object can move in a circle at different speeds.

centripetal acceleration
The acceleration of anything moving at a constant speed in a circle is towards the center of the circle.
When the direction changes. A simple case is an object moving in a circle, at constant speed.
friction
The force toward the centre of the circle is called the centripetal force. centrpetal acceleration.
If body is moving in a circle with uniform or constant speed its acceleration will be uniform as velocity i.e. to say direction is changing at every point.
Nein. If it's moving, by definition it has non-zero velocity.
It can be said that the net force applied on the object is zero or that the object is in translational equilibrium. Keep in mind that these terms can also be applied if the object is moving at a constant velocity.
In toward the center of the circle.
