To calculate the change in velocity (Δv) from the change in time (Δt) and the distance traveled (Δd) by an object, you can use the following equation:
Δv = Δd / Δt
The formula above represents the average velocity of an object over a given time interval. It calculates the change in velocity by dividing the change in distance by the change in time.
It's important to note that this equation gives you the average velocity over the entire time interval. If you need to determine the instantaneous velocity at a specific moment, you would need to use calculus and consider the object's acceleration. The equation above assumes constant velocity over the given time interval.
Remember to use consistent units for distance (Δd) and time (Δt) to obtain the velocity in the correct units. For example, if the distance is given in meters (m) and the time in seconds (s), the resulting velocity will be in meters per second (m/s).
