How are velocity and acceleration similar?
There are a number of similarities and differences between velocity and acceleration.
Both velocity and acceleration help us describe the motion of objects.
Both velocity and acceleration are rates of changes of something with respect to time. While velocity is the rate of change of position, the acceleration is the rate of change of velocity.
or, velocity, v = delta x/delta t and acceleration, a = delta v/delta t
Both velocity and acceleration have a time component. They measure a change taking place over a finite time interval.
Both acceleration and velocity are vector quantities. This means that they are described in terms of magnitude and direction. In comparison, speed is a scalar quantity and is described by its magnitude only, without any reference to direction.
Both velocity and acceleration can be zero during a motion. Circular motion represents a scenario with zero velocity (for every completed circle), while motion with constant velocity will have zero acceleration.
Hope this helps.
