* Velocity is a vector: Velocity has both magnitude (speed) and direction. Displacement is also a vector, but mass is a scalar (it only has magnitude).
* Velocity needs time: Velocity is the rate of change of displacement over time. You need to know how long it took for the object to move that distance.
Here's how to think about it:
Imagine two objects:
* Object A: A 1 kg ball moves 10 meters in 2 seconds.
* Object B: A 5 kg rock moves 10 meters in 5 seconds.
Both objects have the same displacement (10 meters), and different masses, but their velocities are different:
* Object A: Velocity = 10 meters / 2 seconds = 5 meters per second
* Object B: Velocity = 10 meters / 5 seconds = 2 meters per second
To calculate velocity, you need:
* Displacement (Δx): The change in position of the object.
* Time (Δt): The time taken for the change in position.
Formula:
Velocity (v) = Δx / Δt
Example:
If a car travels 100 meters in 10 seconds, its velocity is:
v = 100 meters / 10 seconds = 10 meters per second
