average acceleration
The average acceleration is a measure of how an object’s velocity changes over a specific period of time
The average acceleration is a measure of how an object’s velocity changes over a specific period of time. It is defined as the change in velocity divided by the time taken for that change to occur.
The formula for average acceleration is:
Average acceleration = (final velocity – initial velocity) / time
To calculate the average acceleration, you need to know the initial velocity, final velocity, and the time interval over which the change in velocity occurs.
Let’s say an object starts with an initial velocity of 10 m/s and after 5 seconds, its velocity increases to 30 m/s. We can use this information to find the average acceleration.
Initial velocity (u) = 10 m/s
Final velocity (v) = 30 m/s
Time (t) = 5 seconds
Using the formula, we have:
Average acceleration = (final velocity – initial velocity) / time
= (30 m/s – 10 m/s) / 5 s
= 20 m/s / 5 s
= 4 m/s²
Therefore, the average acceleration of the object is 4 m/s².
It is important to note that acceleration is a vector quantity, meaning it has both magnitude (the numerical value) and direction. In our example above, the direction of acceleration would be in the same direction as the change in velocity, which is positive because the velocity increased.
