No.
No, a particle cannot accelerate if its speed is constant. Acceleration is the rate of change of velocity, and if the speed (magnitude of velocity) remains constant, then the acceleration is zero.
The term for the point at which an object will not accelerate any more is called terminal velocity. At terminal velocity, the forces of air resistance and gravity are balanced, resulting in a constant velocity.
An object can accelerate even if it is moving at a constant speed if the direction of its velocity changes. Acceleration is defined as a change in velocity, which includes changes in speed, direction, or both. For example, a car moving in a circle at a constant speed is accelerating because its direction is constantly changing.
If forces on an object are balanced, the object will not accelerate - i.e., its velocity won't change.
The question is inherantly flawed. A car traveling at a constant speed cannot accelerate, if it could it's speed would not be constant. "Constant speed" means that speed is not increasing or decreasing but remain consistent over time. For example, if you cover 10 feet during each second, your speed is constant. "Constant velocity" implies constant speed, but it has an additional constraint: you can't change your direction. If you travel constantly at 10 feet per second in a straight line, then your speed is constant and your velocity is constant. But if you travel constantly at 10 feet per second in a wiggly line (or a circle, or anything not straight), then your speed is constant but your velocity is NOT constant. If you travel at a constant speed but change direction, velocity is changed. Or if you travel in the same direction but change the speed, velocity is changed. Average speed is is easier: distance/time So, your question should read: Why can a car traveling at an average speed accelerate, but a car traveling at constant speed cannot? Or Why am I asking the wrong questions?

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.

Yes, it's direction may be constantly changing which would mean it is still accelerating.
acceleration is change in velocity.. and velocity constantly changes in circular motion, as the direction constantly changes. This constant change in velocity causes the object to accelerate.
Acceleration means the velocity changes. Velocity is made up of speed and a direction, so if only the direction changes, the velocity still changes, and therefore there is acceleration. The typical example is moving around in a circle.

A balanced force is either not moving or at a constant velocity
An object can accelerate while still traveling at a constant speed if it changes direction. Acceleration is the rate of change of velocity, so even if the speed remains constant, a change in direction would still require acceleration.
velocity increases as it falls due to the force of gravity acting on it. Since there is no air resistance in a vacuum, the object will continue to accelerate until it reaches its terminal velocity or hits the ground.
