Acceleration is defined as the rate at which an object changes its velocity. Velocity is a vector quantity, meaning it has both magnitude (speed) and direction. Therefore, acceleration can result from any change in velocity, which includes changes in speed, changes in direction, or both.<\/p>\n\n\n\n\n
When an object speeds up, its velocity increases, and it experiences positive acceleration. For example, when a car accelerates from rest, it is increasing its speed, which results in a positive change in velocity.<\/li>\n\n\n\n
Acceleration can also occur when an object slows down. This is called negative acceleration or deceleration. For instance, when a car applies brakes, it reduces its speed, causing the velocity to decrease over time. The rate at which the car slows down is considered negative acceleration.<\/li>\n\n\n\n
Acceleration does not require a change in speed. If an object changes direction, its velocity changes, even if its speed remains constant. A classic example is an object moving in a circular path, like a car turning around a curve. Although the speed of the car may stay the same, its direction is changing continuously, which means it is undergoing acceleration. This type of acceleration is called centripetal acceleration.<\/li>\n<\/ol>\n\n\n\n![\"\"](\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner6-333.jpeg\")
