Understanding the Basics
* Displacement: The change in position of an object. It's a vector quantity, meaning it has both magnitude and direction.
* Time: The duration over which the displacement occurs.
Formulas
* Average Velocity:
* Formula: Average Velocity = Displacement / Time
* Units: meters per second (m/s), kilometers per hour (km/h), etc.
* Instantaneous Velocity: The velocity of an object at a specific point in time.
* Calculation: Requires calculus (derivatives) to determine the rate of change of position at a particular instant.
Example: Calculating Average Velocity
Let's say a car travels 100 meters east in 10 seconds.
1. Displacement: 100 meters east (positive direction)
2. Time: 10 seconds
3. Average Velocity: (100 meters east) / (10 seconds) = 10 meters per second east
Important Notes:
* Direction Matters: Velocity is a vector, so always specify the direction (north, south, east, west, etc.).
* Speed vs. Velocity: Speed is the magnitude of velocity. It tells you how fast something is moving, but not in what direction.
* Constant Velocity: An object moves with constant velocity if its speed and direction remain the same.
