Acceleration is defined as the rate of change of velocity of an object with respect to time. It indicates how quickly an object's velocity is changing. In physics, acceleration can occur as a result of an increase or decrease in speed, or a change in direction.
Mathematically, acceleration (\(a\)) can be calculated using the formula:
\[
a = \frac{\Delta v}{\Delta t}
\]
where:
- \(\Delta v\) is the change in velocity,
- \(\Delta t\) is the change in time.
Acceleration is a vector quantity, which means it has both magnitude and direction. It is typically measured in units of meters per second squared (m/s²) in the SI system.
There are different types of acceleration, such as:
- **Uniform acceleration**: the acceleration is constant over time.
- **Non-uniform acceleration**: the acceleration varies over time.
In summary, acceleration describes how quickly an object's velocity is changing and is a fundamental concept in the study of motion in physics.
