* Change in speed: The object is speeding up or slowing down.
* Change in direction: The object is changing its direction of motion, even if its speed remains constant.
Therefore, an object is accelerating if any of the following conditions are met:
* Increasing speed: A car speeding up on a highway.
* Decreasing speed: A car braking to a stop.
* Changing direction: A car turning a corner at a constant speed.
* Changing both speed and direction: A ball thrown in the air follows a curved path, both speeding up and changing direction.
Important Note: Even if an object is moving at a constant speed in a straight line, it is not accelerating. This is because its velocity is not changing.
