The effect of increasing the height of the track on the acceleration of the object is that more work is required to accelerate. It increases the gravity.
On earth, the mass of an object has no effect whatsoever on its acceleration due to the force of gravity. All objects fall with the same acceleration, regardless of their mass. Any observed difference is due entirely to air resistance.
When its speed is increasing
If your acceleration is increasing then by default your velocity has to increase. Acceleration = velocity/time so if acceleration is increasing the velocity is also increasing... And just for fun, just as the change in distance is velocity, and change in velocity is acceleration with respect to time, the change in acceleration with respect to Time is called a jerk
not if the object isn't move, no
angular acceleration

goes faster

angular acceleration
Velocity basically means how fast you are going. Acceleration means how much your speed is increasing. So if there is zero velocity that means the object is not moving. If there is zero acceleration, that means that the speed is not increasing but there is actual speed and the object is not increasing it's speed what ever that may be.
Either of these is referred to as positive acceleration: A) the object's velocity is increasing in the frame of reference B) the object is being moved in a positive direction in a coordinate plane
If an object is sustaining a constant velocity it has 0 acceleration, because acceleration is either increasing or decreasing speed.
increasing the mass of the object, keeping the net force constant
