Study Notes
Types of Motion
- Uniform motion: Occurs at a constant speed moving in a straight line.
- Non-uniform motion: Involves changes in speed, direction, or both.
Acceleration Concepts
- Acceleration: Defined as the change in velocity per unit time.
- Uniform acceleration: Velocity changes by equal amounts in equal time intervals while moving in a straight line.
- Non-uniform acceleration: Velocity changes by unequal amounts in equal time intervals, involving changes in direction or both.
Key Formulas in Motion
-
Velocity time formula: ( v = u + at )
- Where ( v ) is final velocity, ( u ) is initial velocity, ( a ) is acceleration, and ( t ) is time.
-
Position time formula: ( s = ut + \frac{1}{2} at^2 )
-
Position velocity formula: ( 2as = v^2 - u^2 )
Graphical Interpretations
- Distance time graph: The slope indicates speed.
- Velocity time graph: The slope indicates acceleration.
- Area under the velocity time graph: Represents the distance traveled.
