The rate at which an object's velocity changes with time
is called Acceleration.
The rate at which an object's velocity changes with time is known as acceleration.
To calculate the average acceleration of an object, you need to know the change in velocity and the time interval over which the change occurs. The formula for average acceleration is:
acceleration = (change in velocity) / (time interval)
The change in velocity can be found by subtracting the initial velocity from the final velocity. The time interval is the duration it takes for the velocity to change.
If you have a graph of velocity versus time, you can find the acceleration at a specific instant by calculating the slope of the tangent line to the curve at that point. This is done by finding the change in velocity over a very small time interval, approaching zero.
Accelerations can be positive or negative, depending on whether the velocity is increasing or decreasing, respectively. If an object is moving in the opposite direction of its positive velocity, the acceleration will also be negative.
Units for acceleration are typically measured in meters per second squared (m/s²) in the International System of Units (SI).
