Acceleration is the rate at which an object changes its velocity. It is a vector quantity, meaning that it has both magnitude and direction. In other words, acceleration measures how quickly an object's velocity changes over time, either by speeding up, slowing down, or changing direction. It can be calculated by dividing the change in velocity by the change in time. The standard unit of acceleration is meters per second squared (m/s²).
Provide an example of accleration?
An example of acceleration can be observed when a car starts from rest and begins to move forward. Initially, the car has a velocity of 0 m/s. As the driver presses the accelerator, the car's velocity gradually increases. The rate at which the velocity increases is the acceleration. If the car reaches a velocity of 10 m/s after 5 seconds, the acceleration can be calculated as the change in velocity divided by the change in time, which is (10 m/s - 0 m/s) / 5 s = 2 m/s². Therefore, the car is accelerating at a rate of 2 meters per second squared.
