How Things Move? Learn The Science Behind Motion - Physics Quiz

In physics, motion is the phenomenon in which an object changes its position over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time. How Things Move? Learn The Science Behind Motion in this Physics Quiz
