**Forces and Motion**

**Velocity and Acceleration**

SPEED= how fast you are going (e.g 30 m/s or 10 mph)

VELOCITY= how fast you are going, but you MUST include a direction (e.g 30 m/s North)

**Speed, Distance and Time**

*The Formula *

**Average Speed= Distance/ Time **

**TIP;**To use this triangle just cover up the word you want to find E.g. If you're looking for time cover up time and you are left with distance/time, This is the equation needed to find out time.

**EXAMPLE QUESTION; **

**A girl cycles for 3 hours at a speed of 40km/s. How far does she Travel? Give your answer in km.**

* Step 1:* Cover up distance on the formula traingle to find the equation. You should see it is

**Speed x Time**

** Step 2:** Use…
