MOTION:
Motion is the change in position of an object with respect to its surroundings in a given interval of time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, and speed. ... One can also speak of motion of images, shapes and boundaries...SI unit of motion is m/sec...
SPEED:
Speed is the distance traveled per unit of time. It is how fast an object is moving. Speed is the scalar quantity that is the magnitude of the velocity vector. It doesn't have a direction. Lower speed means it is moving slower...SI unit of speed is m/sec...
DISPLACEMENT:
Distance is a scalar quantity. Displacement is an object's change in position, only measuring from its starting position to the final position. ... If your starting and ending position are the same, like your circular 5K route, then your displacement is 0. In physics, displacement is represented by Δs...
