Difference between velocity and acceleration class 9

In this article, we shall take a look at the major differences between Acceleration and Velocity.

Velocity and acceleration are the two key concepts which are always discussed while studying motion. Velocity can be understood as the speed of a moving body in a particular direction whereas acceleration is any change in the velocity of the object, with respect to time. Motion implies movement; it is the act of moving or more specifically, the change in position of the body, concerning time. Whenever you walk, run or drive you are actually in motion and not only this, flying of birds, swimming of fishes, flowing of water from the river, falling of leaves from trees, rotation and revolution of the earth, is also motion. For a layperson, these two terms are one and the same thing, but in physics, there are subtle differences between velocity and acceleration. Basis for Comparison Velocity Acceleration Meaning Velocity implies the speed of an object, in the given direction. Acceleration alludes to any change in the velocity of the object with respect to time.

Sachin drives to work everyday in his scooty. One day, he notices a KTM race past him. In order to catch up with him, he increases his throttle. Now he finds himself alongside the KTM. Sachin then becomes tired of chasing and decides to slow down his scooty; so he applies the brakes—gradually slowing down and coming to rest. In other words, one can say that Sachin has accelerated in the first case—increasing his speed. On the other hand, while slowing down, he has decelerated. In this article, we will explore the differences between velocity and acceleration. Velocity is defined as the change in displacement divided by the time taken. It is a vector quantity. Velocity can be positive or negative.

As velocity is an example of vectorit has direction and magnitude. Velocity includes direction, which means an object moving at the same speed in different directions will have different velocities. The acceleration of the object.

Difference between velocity and acceleration : Velocity is the rate of change of an object's displacement over time, indicating its speed and direction. Acceleration, on the other hand, is the rate of change of velocity over time, depicting how quickly an object's velocity is changing. For a comprehensive understanding, read the below article on the difference between velocity and acceleration. To explore differences on various topics, visit our dedicated ' Key Differences ' page. Velocity is the rate of change of displacement with respect to time. It is a vector quantity, indicating both speed and direction. Acceleration is the rate of change of velocity with respect to time.

Displacement is a vector quantity. It has both magnitude and direction. At first observe Picture-I. An object moves 3 metre from X to Y , then 4 metre from Y to Z. Now also observe Picture-II. Consider the following cases one by one — Case-1 : Object moves from A to B , here both linear distance covered and displacement is 30 metre. Speed is the distance covered by a moving object in a second. It may be uniform or non-uniform.

An object is said to be accelerated if there is a change in its velocity. The change in the velocity of an object could be an increase or decrease in speed or a change in the direction of motion. A few examples of acceleration are the falling of an apple, the moon orbiting around the earth, or when a car is stopped at the traffic lights. Through these examples, we can understand that when there is a change in the direction of a moving object or an increase or decrease in speed, acceleration occurs. Acceleration is a vector quantity as it has both magnitude and direction. It is also the second derivative of position with respect to time or it is the first derivative of velocity with respect to time. Read More: SI unit of Acceleration. So can we have a situation when speed remains constant but the body is accelerated? Actually, it is possible in a circle where speed remains constant but since the direction is changing hence the velocity changes, and the body is said to be accelerated. The average acceleration over a period of time is defined as the total change in velocity in the given interval divided by the total time taken for the change.

For example, consider a car driving on a road at a constant speed of 60 miles per hour in the east direction. Thank you! The magnitude of it represents the speed of an object, while the direction represents the direction of motion. Vector quantities can be added and subtracted, and their operations follow the rules of vector arithmetic. It allows for the prediction and modeling of complex motion scenarios, such as projectile motion or orbital mechanics. It is a vector quantity, indicating both speed and direction. There can be two types of acceleration, which are:. Amount of substance. Some of the most common applications include:. Difference Between Velocity and Acceleration Aspect Velocity Acceleration Definition Velocity is the rate of change of displacement with respect to time. Though the motion variation is slight, they all have a different notion. Area Under the Curve The area under the velocity-time graph indicates displacement. In this example, the velocity of the car is 10 meters per second in the direction from position A to position B. Velocity is a measure of an object's speed and direction of motion.

Can you provide an example to differentiate between velocity and acceleration? Its velocity remains positive in the upward direction but the acceleration is negative in the downward direction. Velocity determines the speed of the moving object along with the direction of motion. Definition of Speed. Vector Vector What is it? Importance in Engineering Velocity considerations are vital in designing transportation systems and calculating fluid flow. NEET Courses. What is it? It aids in calculating the net force acting on an object, as acceleration is directly proportional to the applied force and inversely proportional to the object's mass. As we have seen before, velocity is said to be the speed with direction.
