Acceleration is not a change in speed, but a change in velocity. Velocity is, unlike speed, a vector, and so as the direction of velocity changes there must be an acceleration to cause that change.
No. An object traveling at a constant velocity is not accelerating.
An accelerating object is one that is changing in either speed or direction. Thus any object that is turning is accelerating while maintaining a constant speed.
Since acceleration involves a change in velocity, and object might be accelerating even though its speed is constant.
No. An object is accelerating if it is changing speed or direction of travel. Since the person in question is running at a constant speed in a straight line, they are not accelerating.
If the object is not moving, or is traveling at a constant velocity, all forces acting on the object are equal and opposite to each other. If the object is accelerating (speeding up, slowing down, or changing direction) the forces are not balanced.
No. An object traveling at a constant velocity is not accelerating.
An accelerating object is one that is changing in either speed or direction. Thus any object that is turning is accelerating while maintaining a constant speed.
An object with a constant (vector)velocity is not accelerating. An object with a constand (scalar)speed can actually be accelerating, a car with a constant speed that passes around a corner is changing direction and is subjected to a lateral acceleration.

No. Acceleration is any change of velocity.But its speed can be constant.
When an object is not accelerating at all. It has constant velocity.
If the object is not moving, or is traveling at a constant velocity, all forces acting on the object are equal and opposite to each other. If the object is accelerating (speeding up, slowing down, or changing direction) the forces are not balanced.

Not accelerating. It could be stationary or moving at a constant speed.
If the force acting upon an object are balanced then the object must not be accelerating
