Linear acceleration is the rate at which an object's velocity changes over time in a straight line. It is the increase or decrease in an object's speed as it moves in a straight line. Linear acceleration is measured in meters per second squared (m/s^2).

Linear acceleration is used in a variety of real-life applications, including:

Transportation: Linear acceleration is used to measure the speed and acceleration of cars, trains, airplanes, and other vehicles.

Athletics: Linear acceleration is used to measure the speed and acceleration of athletes, such as sprinters and jumpers.

Physics: Linear acceleration is used in physics to describe the motion of objects in a straight line.

Robotics: Linear acceleration is used in robotics to control the motion of robots in a straight line, such as in factory automation.

Space exploration: Linear acceleration is used in space exploration to describe the motion of spacecraft in a straight line.

The formula for determining the acceleration is defined as:

\(a\) \(=\) \(\dfrac{v_2 - v_1}{t}\)

\(v_1\): the initial velocity/speed

\(a\): the acceleration

\(v_2\): the final velocity/speed

\(t\): the time in seconds

The SI unit of acceleration is: \(meter/square second \text{ }(m/s^2)\)
