What is the biggest difference between speed and velocity?

Both include distance and time, but velocity also includes direction.

acceleration

Change in velocity; An object is accelerating if it starts, stops, speeds up, slows down, OR changes direction

speed

How fast an object is moving, must have both distance and time

velocity

Speed (distance and time) of an object plus its direction

A subway travel East at 45 km/hr

Velocity

Acceleration formula

a=vf-vi/t

A runner slows to a stop as he gets tired

acceleration

Change in speed Slow down Change in velocity Speed up Change direction

acceleration
