If anything is traveling at constant velocity, then the net force acting on it must be zero.+++Strictly, it is travelling at constant speed, not velocity, because you have not specified the directions of the train and the retarding forces acting on it.
Constant acceleration is the resulting motion of forces acting on an unbalanced bicycle.
are constant
The answer is: Water resistence and thrust
It travels in uniform motion when there are no net forces acting on it.
It can be in equilibrium if in constant motion (constant velocity) as no forces are acting on it (no acceleration)
It is in Equilibrium and there are no forces acting on it.
thrust, lift, drag and weight. these are all balanced forces as it is travelling at a constant speed.
An object with balanced forces acting on it is still. An object with unbalanced forces acting on them moves at an non constant velocity. It is possible for an object to have balanced forces acting on it and yet move in a vacuum.
Drag forces are trying to slow the car down. Engine power to the wheels generates force that equals the drag, and keeps the car travelling at a constant speed. The sum of all forces on the car are zero, which is why it is not accelerating or decelerating.
It will have zero force BUT, it WILL have a constant velocity
