Answer: The motion is accelerated.
Step-by-step explanation: Given that the horse is walking along a straight line.
The horse travels 3 m in first second, so its speed is 3m/s.
In the next second, the horse travels 4 m, so its speed is 4 m/s.
In the third second, the horse travels 5 m, so its speed is 5 m/s.
Since the speed of the horse is increasing per second i.e., the speed in not constant, so the motion of the horse is accelerated.
The speed of objects is influenced by a few factors, the amount of force that is being exerted upon them being one of them. The famous physicist Newton was talking about this phenomenon in his famous laws of Newton as well. .. and so on :) then you could explain his laws and which one applies in this case :)
