[tex]↬[/tex]acceleration, rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down. Motion on a circle is accelerated even if the speed is constant, because the direction is continually changing.
Acceleration is the rate at which the velocity of an object changes. It is a vector quantity, meaning that it has both magnitude and direction. The magnitude of acceleration is the amount by which the velocity changes, and the direction of acceleration is the direction in which the velocity is changing.
In physics, acceleration is typically measured in meters per second squared (m/s²). For example, if an object is accelerating at 5 m/s², this means that its velocity is increasing by 5 meters per second every second.
There are two types of acceleration: **constant acceleration** and **variable acceleration**. Constant acceleration occurs when the rate of change of velocity is constant. This means that the velocity of the object is increasing by the same amount every second. Variable acceleration occurs when the rate of change of velocity is not constant. This means that the velocity of the object is increasing by different amounts at different times.
Acceleration is a very important concept in physics. It is used to describe the motion of objects in a wide variety of situations, from the movement of cars to the motion of planets.
Here are some examples of acceleration:
* A car speeding up
* A ball falling from a tree
* The Earth orbiting the Sun
