Speed vs Velocity

How do we discuss HOW FAST an object moves? Let’s start with speed: SPEED is the rate at which an object covers ground. If you’re a math head like me: SPEED is distance divided by time , the distance an object travels in a unit of time. If you are driving 70 mph → you can cover 70 miles in one hour . . . if you are going at a constant speed.

How do we discuss HOW FAST an object moves?

Let’s start with speed:

SPEED is the rate at which an object covers ground.

If you’re a math head like me:

SPEED is distance divided by time , the distance an object travels in a unit of time.

If you are driving 70 mph → you can cover 70 miles in one hour

. . . if you are going at a constant speed.
