Jonathan questions why the acceleration vector is considered perpendicular to the tangent vector when velocity is constant, citing confusion with the example of a parabolic function. Some participants assert that acceleration is zero when velocity is constant, suggesting a misunderstanding of the distinction between velocity and speed.
The discussion revolves around the concepts of velocity and acceleration vectors, particularly focusing on how to calculate acceleration from two velocity vectors and the interpretation of vector components. Participants explore the differences in vector addition and subtraction methods, as well as the implications of vector direction in motion.
Acceleration always has a direction so should always be taken to be a vector. If you only mean the magnitude then that's the magnitude of the acceleration.
By knowing the velocity vector at a specific instant, one can determine the angular frequency (ω) and predict the position vector at any future time using the derived equations. The acceleration vector can also be utilized similarly, reinforcing the interconnectedness of these vectors in circular motion.

The acceleration vector of this plate would point upward, but why is the gravitation acceleration vector on Earth always depicted downwards? obviously the gravitational force is downward, but if i accelerated an object to the left, i would feel a force opposite to the direction of acceleration.
The formula to calculate the magnitude of acceleration vector in physics is a (ax2 ay2 az2), where ax, ay, and az are the components of acceleration in the x, y, and z directions, respectively.
