Chapter 4 - Movement Analysis
Uncover The Secrets Of Motion With Kinematics
Table of content
Kinematics - the motion maestro ๐บ๐
- Definition: Study of motion - how a body or object changes its position.
- Types of Motion
- Linear Motion (Straight Line): Imagine an ice hockey puck zooming straight across the ice. ๐
- Curvilinear Motion (Curve): Like a shot-put making a big arc in the sky before it lands. ๐๐
- Angular Motion (Rotational): Think of a gymnast flipping around a high bar like they're the Earth rotating around its axis. ๐คธโ๏ธ๐
- General Motion: Combo of linear + angular. Most common in sports. Even if you're sprinting straight, your limbs are rotating! ๐โ๏ธ
Fun Fact: Even when you're just running in a straight line during a race, your legs are spinning like the wheels on a car! ๐
Vector vs scalar - the dynamic duo ๐งญ
- Vector: Has size and direction. If you're walking 5km to the North, the distance and North part make it a vector! ๐ถโ๏ธ๐งญ
- Scalar: Only size. If you've eaten 3 pizzas - that's a scalar (and also impressive). ๐
- Mixing & Matching
- Same direction vectors? Just add 'em up!
- Different direction vectors? You'll need some fancy math.
- Scalars? Simple arithmetic works. Add, subtract, multiply, divide.
Think of it this way: A scalar is like telling someone how many apples you have. A vector is telling them how many apples you have and where you're throwing them!
