Distance How far you have traveled between two positions. It is always positive. It is a scalar quantity.
Displacement change in position. It is the straight line distance between your starting position and ending position. It is equal to Final position minus initial position. It can be positive or negative. It is a vector quantity.
Scalar Quantity that only requires magnitude (how big)
Vector Quantity that requires both magnitude (how big) and direction.
Speed How fast something is moving. It is equal to distance divided by time. It is a scalar quantity.
Velocity The rate at which position changes. It equal to displacement divided by time. It is a vector quantity.
Newtons 1st Law, AKA law of inertia an object at rest will stay at rest and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by a unbalanced force.
