WebThe acceleration vector is a → = a 0 x i ^ + a 0 y j ^. Each component of the motion has a separate set of equations similar to Equation 3.10 – Equation 3.14 of the previous chapter on one-dimensional motion. We show only the equations for position and velocity in the x - and y -directions. WebAcceleration is a change in velocity, either in its magnitude —i.e., speed—or in its direction, or both. In uniform circular motion, the direction of the velocity changes constantly, so there is always an associated acceleration, even though the speed might be constant.
