Velocity
Velocity is a physical quantity that describes the rate of change of an object’s position. It is a vector quantity, meaning it has both magnitude and direction. Velocity is defined as the displacement of an object divided by the time taken to cover that displacement. In equation form, velocity (v) can be expressed as:
v = Δx / Δt
where Δx represents the change in position and Δt represents the change in time. The SI unit of velocity is meters per second (m/s).
Velocity provides information about both the speed and direction of an object’s motion. If the velocity of an object is constant, it means the object is moving at a steady speed in a straight line. However, if the velocity changes, the object’s motion can be described as accelerating or decelerating.
It’s important to note that velocity is distinct from speed, which is the magnitude of velocity without considering its direction. Velocity takes into account the displacement and direction, while speed only considers the magnitude of the displacement.
Velocity is a fundamental concept in physics and is extensively used in kinematics, dynamics, and various other branches of the subject. Understanding velocity is crucial for analyzing the motion of objects, predicting their future positions, and solving problems related to motion and forces.

Case Study on Physics syllabus Velocity
Case Study: Velocity in Projectile Motion
Let’s consider a case study on velocity in the context of projectile motion. Projectile motion refers to the motion of an object that is launched into the air and moves under the influence of gravity alone. A classic example of projectile motion is the motion of a ball thrown horizontally off a cliff.
Scenario: A baseball player throws a ball horizontally off a cliff with an initial speed of 20 m/s. The cliff is 30 meters high, and the ball lands a horizontal distance of 50 meters away from the base of the cliff. We will analyze the velocity of the ball at various points during its flight.
- Initial velocity: Since the ball is thrown horizontally, the initial velocity in the horizontal direction (Vx) is constant and remains at 20 m/s throughout the motion. In the vertical direction, the initial velocity (Vy) is 0 m/s because the ball is not initially moving up or down.
- Maximum height: As the ball moves upward, its vertical velocity decreases due to the influence of gravity. At the highest point of its trajectory, the ball momentarily stops moving upward before it starts to descend. At this point, the vertical velocity is 0 m/s.
- Time of flight: The total time of flight can be determined using the vertical motion of the ball. The time taken for the ball to reach the highest point is determined by the initial vertical velocity and the acceleration due to gravity. Similarly, the time taken for the ball to reach the ground is determined by the time it takes to fall from the maximum height. This total time of flight is denoted as “t” and can be calculated.
- Final velocity at impact: When the ball lands on the ground, both the horizontal and vertical components of velocity contribute to the resultant velocity. The horizontal velocity remains constant at 20 m/s, while the vertical velocity increases due to the acceleration from gravity. The resultant velocity at impact can be calculated using vector addition.
By analyzing the case study, we can observe how velocity is affected by gravity during projectile motion. While the horizontal component of velocity remains constant, the vertical component changes due to the influence of gravity, resulting in a parabolic trajectory. Understanding the principles of velocity in projectile motion helps explain the range, maximum height, and other characteristics of the ball’s flight.
