The question is, if not a maelstrom, certainly a melange at least.
Especially noteworthy is the part where "acceleration of a body changes
at constant velocity".
Acceleration is the rate of change of velocity. If velocity is constant, then there is
no acceleration. If velocity changes at a constant rate, then acceleration is constant.
Velocity would have to change at a rate that changes, in order to have a changing
acceleration.
Now, what is it you're looking for ? A "linear or circular motion equation" ? There are
oodles of them, describing the relationship among the position, displacement, speed,
velocity, and acceleration, in one, two, or three dimensions, in rectangular, polar, and
spherical coordinates, for linear motion, and an entire separate set of equations for
circular motion.
An object in uniform circular motion undergoes constant acceleration but moves at constant "speed".Constant "velocity" means no acceleration.
V = constant Speed = constant Direction = constant Acceleration = 0
No. It is a matter of definition. Acceleration is defined as a change of velocity. Technically, one must distinguish between velocity and speed. Velocity is a vector and includes the information about the magnitude (speed)and direction. One can have a constant speed and an acceleration (as in circular motion) but, by definition, constant velocity means zero acceleration.
No. The velocity and acceleration are not zero because the direction is changing, thus the velocity and acceleration is changing.
The magnitude of the velocity will be constant however the direction will be constantly changing. The acceleration will remain constant towards the centre of the circle
If your velocity is constant, then your acceleration is zero.
Objects moving in uniform circular motion will have a constant speed, and two objects with the same acceleration have a constant velocity.
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 change of velocity. If velocity is constant, then acceleration is zero.
Yes. If a body has a constant velocity there is no acceleration, but if the velocity is changing there is acceleration present.
Yes, it is. Trajectory also depends of direction of acceleration, not only it's magnitude. When you consider circular orbit, the agnitude of centripetal acceleration is constant, but the vector directions changes every moment to point constantly at the center.
If the velocity is constant then there is no acceleration. The acceleration is zero.
