When an object has positive acceleration, some people assume this means that an object's velocity is pointing in the positive direction and is gaining a larger magnitude.

1) In one paragraph, describe an example of motion in which the acceleration is positive but the assumption above is not true. 2) Justify your answer with some made-up numerical values for initial velocity, final velocity, and time that can be used to compute a positive acceleration.

One dimensional motion describes the changes in the position of an object over time in terms of its displacement, velocity, and acceleration in one direction. The motion in that direction is independent of the displacement, velocity, and acceleration associated with any of the perpendicular directions. For example, the acceleration due to gravity near the surface of the earth has a value of 9.8 m/s2, downward. This affects the vertical motion of an object but has no effect on the motion...

Your task will be to derive the equations describing the velocity and acceleration in a polar coordinate system and a rotating polar vector basis for an object in general 2D motion starting from a general position vector. Then use these expressions to simplify to the case of non-uniform circular motion, and finally uniform circular motion. Here's the time-dependent position vector in a Cartesian coordinate system with a Cartesian vector basis: ⃗r(t)=x (t) ̂ i+y(t) ̂ j where x(t) and y(t)...
