Is it possible that a body moving with uniform speed is said to be accelerated.
Answers
Acceleration is a change in velocity. Velocity is a vector. This means that in addition to a speed (meters per second, miles per hour, etc.) it has a direction. Speed, by comparison, is a scalar - it lacks direction, thus is always positive whereas velocity could be positive going forwards and negative going backwards.
Now consider a child swinging a ball on a circle on the end of a string. The child could do this at a constant speed, yet the direction is constantly changing. Since the direction is changing and direction is a component of velocity, the velocity is also changing. Acceleration is defined as a change in velocity with over time, thus the ball has acceleration (this is called centripetal acceleration). Another way to think of it is what would happen if the ball detached from the rope? The ball would cease its circular motion immediately and go off in a straight line. This means that the rope HAS to be pulling the ball for it to maintain its circular motion. Actually, it’s pulling it towards the child in the center of the rope similarly to how earth constantly pulls the moon towards it. In fact, if not for friction, air resistance, etc., once swung, the ball would continue to orbit the girl indefinitely with the tension in the rope providing the same type of “inwards” force as gravity (I’m hoping that preemptively answered any gravity related questions).
“But… I meant going straight forwards!”
Then no. Acceleration is a change in velocity. Since you’re going in a straight line and forwards, the direction component of velocity is immaterial and velocity becomes interchangeable with speed, allowing us to define acceleration (in this example only!) as a change in speed. You cannot be at a constant speed and simultaneously be changing your speed (accelerating).
