Easy: Velocity at a time
Velocity is the derivative of position, v(t) = s′(t), and acceleration is the derivative of velocity, a(t) = v′(t) = s″(t). The object is at rest when v(t) = 0, moving forward when v(t) > 0 and backward when v(t) < 0.
s(t) is the position of an object in meters after t seconds.
Tip: tick “Step-by-step answer key” in the generator to print each step for marking.
Velocity is the derivative of position, and acceleration is the derivative of velocity. Each tells how fast the one before it is changing.
The object is momentarily at rest. If the velocity changes sign there, the object turns around.
