We all grew up thinking "acceleration" means "speeding up". It doesn't.
"Acceleration" means the speed or the direction is changing.
So if a moving object is speeding up, slowing down, or keeping a constant speed
on a path that's curving or bending, then there's acceleration going on.
You can be accelerating and traveling at a constant speed if you change directions.
If you are traveling at a constant speed with changing direction there is a change in velocity, so you are accelerating.
No. 'Acceleration' means a change in speed or direction over time. If the car is moving at a constant speed in a constant direction, then it isn't accelerating.
No, the magnitude will be constant, but the direction of the momentum will change to reflect the direction of the velocity.
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.

Slope at any point is speed. if slope is constant (staight line)then speed is constant; if curved up speed is accelerating. If curved down it is decelerating
That's correct.
true
No it does not because once you change direction you do not have a constant speed.
No, the magnitude will be constant, but the direction of the momentum will change to reflect the direction of the velocity.
A constant speed means that the horse is neither accelerating nor decelearating Speed is a scalar which means it has a magnitude but no direction, while acceleration is a vector so it has both a magnitude and a direction. As the magnitude of the speed remains constant, the speed is constant but since the direction the horse travels in changes that horse is in fact accelerating.

if a train is accelerating on a curved track at a constant speed is the train acceeratng
