Acceleration vs Velocity


Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity. As velocity is an example of vector, it has direction and magnitude. So we can explain the acceleration in any of these three ways:

  1. a change in direction (from East to North-East)
  2. a change in both speed and direction (from 34 km/h East to 12 km/h West)
  3. a change in speed, the magnitude of the velocity (from 34 km/h to 67 km/h)

Newton’s Second Law of Motion

The acceleration of an object is directly proportional to the force acting on it and inversely proportional to its mass. Simply put, the force causes an object to accelerate, while the object’s mass resists acceleration.

  1. He is very good learning app .in this application all concept are clearly. So it’s good

  2. Thanks for your answer about the differences 😮😮😍😍😇😇
