* Velocity is a vector quantity: Velocity tells us both the speed (how fast an object is moving) and the direction of its motion. To determine the speed, we need to know how far something traveled (distance) and how long it took to travel that distance (time).
* The formula: Velocity is calculated using the following formula:
Velocity (v) = Distance (d) / Time (t)
This means to find the velocity, you divide the total distance traveled by the total time taken.
* Examples:
* Scenario 1: A car travels 100 kilometers in 2 hours. Its velocity is 100 km / 2 hours = 50 km/h.
* Scenario 2: A ball is thrown straight up and reaches a height of 10 meters in 2 seconds. Its velocity (upward) would be 10 meters / 2 seconds = 5 meters/second.
In summary:
Knowing the distance and time traveled is essential because:
1. It allows us to calculate the speed of the object.
2. Combining speed with the direction of motion gives us the complete picture of the object's velocity.
