Here's a breakdown:
* Speed: This is the rate at which something is moving, often measured in meters per second (m/s) or kilometers per hour (km/h).
* Direction: This tells you which way the object is moving, such as north, south, east, west, or at a specific angle.
Examples:
* A car traveling at 60 km/h east has a velocity of 60 km/h east.
* A ball thrown upwards at 10 m/s has a velocity of 10 m/s upwards.
Key points about velocity:
* Constant velocity: An object has constant velocity if it moves at a constant speed in a constant direction.
* Changing velocity: If an object's speed or direction changes, its velocity changes. This means the object is accelerating.
* Negative velocity: Negative velocity simply indicates motion in the opposite direction. For example, a car moving 20 km/h west has a negative velocity relative to a car moving 20 km/h east.
In short, velocity gives us a complete picture of an object's motion, including both its speed and direction.
