Answer 2

Answer:

• 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.
• 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.
• Velocity is the rate at which the position changes. Velocity is a vector quantity.
