In science, velocity is typically defined as the rate at which an object changes its position in a particular direction. Mathematically, velocity is calculated by dividing the change in displacement (change in position) by the change in time. The formula for velocity is:
Velocity = Displacement / Time
In equation form, it can be represented as:
v = Δx / Δt
where: v is the velocity, Δx is the change in displacement (final position minus initial position), and Δt is the change in time (final time minus initial time).
It's important to note that velocity is a vector quantity, meaning it has both magnitude and direction. So, in addition to calculating the numerical value of velocity, you also need to specify the direction in which the object is moving.
