Physics is Everywhere!

So, where do we see it, use it, experience it?

- How about your personal experiences???

a) At work

b) Sports

c) In school

d) At play/recreation

Video clips • Curveball, wingsuit, skateboarding,

So, how do we divide physics into parts?First of all, what is the definition of Physics…

Physics = Is the scientific study of matter and energy and how they interact with each other.

Parts/fields of Physics = There are many, can you give specific examples?

PHYSICS AND MOTION• Name different ways to describe motion.

– Speed/Velocity– Acceleration– Position– Time

The 3 things:

1. Position = This is precisely where an object is located.

2. Speed = Precisely how fast an object is moving.

3. Acceleration = Precisely how fast an object’s speed is changing. (This is usually the most difficult for students)

* In the study of motion we will be trying to describe, explain and predict motion as simply and precisely as possible!

What about ‘Motion’ in SPORTThis is known as Biomechanics.• Why most people move the way they do,

how can you go faster.• How can a figure skater spin in one spot for

so long.• How can a skateboarder perform an ollie? * These are just a few examples that we will

discuss in this unit.

When are we ever going to use this?• Improves scientific literacy – problem solving

skills, distance over time, simple unit conversions.

• Important stepping stone for any course/job that involves simple math/equations – Science/engineering, Trades, Design, Business, Kinesiology.

• It can be fun!

Precision… this is why we did all the sig dig stuff!

• 'Precision' refers to 'the number of significant digits' or the 'number of decimal places' you use when recording the result. Even if the person making a measurement is as accurate as humanly possible, limitations imposed by the measuring instrument, variations in dimensions of the object being measured, and the conditions under which the measurement is being made, dictate that the result should not imply greater precision than circumstances warrant.

NOW, HOW ABOUT SOME SPEED!
