How to Calculate Acceleration
Acceleration is a fundamental concept in physics that describes the rate of change of velocity of an object over time. To calculate acceleration, you can use the following formula:
a = (v_f - v_i) / t
Where:
- a = acceleration
- v_f = final velocity
- v_i = initial velocity
- t = time taken for the change in velocity
To apply this formula, first determine the initial and final velocities of the object. The initial velocity (v_i) is the speed at which the object starts, while the final velocity (v_f) is the speed at which it ends after a certain time period (t).
For example, if a car accelerates from 20 m/s to 60 m/s in 5 seconds, the acceleration can be calculated as follows:
a = (60 m/s - 20 m/s) / 5 s = 8 m/s²
This means the car's velocity increases by 8 meters per second every second.
