A bird is flying north at 5 m/s. The bird veers and travels at 5 m/s east. This happens over a 2 second period. what is the average acceleration (magnitude and direction) during this 2 second interval?
Average acceleration is the rate at which an object changes its velocity over a specific period of time. It is a vector quantity, meaning it has both magnitude (speed) and direction.
Average acceleration can be calculated by dividing the change in velocity by the change in time. The formula for average acceleration is: a = (vf - vi) / t, where a is the average acceleration, vf is the final velocity, vi is the initial velocity, and t is the time interval.
Direction is important in calculating average acceleration because it tells us the direction in which an object is changing its velocity. This is crucial in understanding the overall motion of an object.
The units of average acceleration are typically meters per second squared (m/s^2) in the SI system or feet per second squared (ft/s^2) in the English system.
Average acceleration is calculated over a specific time interval, while instantaneous acceleration is the acceleration at a specific moment in time. Average acceleration takes into account the overall change in velocity, while instantaneous acceleration only considers the velocity at a single point.
