How does Newton's Laws of Motion affect our everyday lives?
Believe it or not but MOTION is one of the most important concepts that affect our everyday lives and understanding it is the key to understanding the world we live in.
1) Distance and Displacement
2) Speed and Velocity
3) Acceleration
4) Forces and Newton's Three Laws of Motion
Motion is Amazing!
The Space Shuttle may reach accelerations of 30 m/s2 and speeds of 28,000 km/h however a cheetah is the fastest animal, reaching accelerations of 20 m/s2 and speeds of 80 km/h.

Motion and its Importance to You (and everyone else)
The reality is that everything is moving all the time. Sit as still as you can. Don't move a muscle. Are you really sitting stationary in your chair right now? Ok so now that you understand that everything is in motion all the time then what do you think would happen if the Earth stopped rotating????????????????? Reference: CS5 Chapter 9 On the Move |
Distance and Displacement
Reference: CS5 9.1) How far is it?
1: Complete the worksheet provided to learn about the difference between distance and displacement. This video will help you understand the difference. If you have any time, you can test your understanding of distance and displacement using the interactive "Vector Walk" |

Usain Bolt's World Championship Memories | I AM BOLT
Why It's Almost Impossible to Run 100 Meters In 9 Seconds | WIRED
|
1. Watch the the youtube video "I AM BOLT".Then complete class activity "How fast can Danebank Girls run?"
2. Read through the information on "Speed and Velocity" on the Physics Classroom website. Make summary notes in your exercise books. 3. Refine your mathematical ability as well as draw a distance versus time graph using the worksheet "Speed and Velocity Problems". 4. Experiment: Using the Ticker Timer to measure Constant Speed. In your books, put the following: a. Paste the experimental sheet into your exercise book b. Put the heading "Questions and Results" in your exercise book. Then complete all steps in your book. There are questions to answer as well as a table and a graph to complete. Make sure ALL steps for the experiment are completed. c. Then put the heading "Conclusion" and list ALL the scientific concepts that you and your group learnt during this experiment about constant speed. NOTE: When drawing graphs, you must use pencil and ruler AND your graph must be at least 1/2 page. 5. Extension - Complete Q1 - 14 Core Science Stage 5 Section 9.2 pg 302. Answers |
Acceleration - Speeding Up and Slowing Down
Reference: CS5 9.3) Speed Up, Slow Down
Reference: CS5 9.3) Speed Up, Slow Down
Acceleration is when the speed of an object changes. If the speed gets larger and larger, then the object is accelerating. However the speed can also get smaller and smaller and then the object is decelerating.
There is a mathematical formula for calculating acceleration Drag car racing is a classic example of extreme acceleration. From a standing start, the drag car must cover a distance of 400 m in as fast as possible time. The jet car does this in about 4.8 seconds which means that it is moving at over 504 km/h (140 m/s). What is the acceleration of this jet car? Once the drag car has finished the 400 m, it needs to slow down and decelerate. The parachutes are deployed and it takes about 5.4 s to stop. What would be its deceleration? |
