Define as a speed of an object in a particular direction. It is a measure of how quickly an object moves, and it includes both the magnitude (speed) and the direction of motion.
The word “velocity” has Latin origins, derived from the Latin word “velocitas,” which means “swiftness” or “speed.” It entered the English language through Middle English.
The space probe achieved an incredible velocity as it hurtled through the cosmos, reaching speeds that were previously thought to be unattainable.
FAQs (Frequently Asked Questions)
How is velocity different from speed?
While both velocity and speed measure how quickly an object is moving, velocity also includes the direction of motion.
How is velocity calculated?
Velocity is calculated by dividing the change in position (displacement) of an object by the time it takes for that change to occur. Mathematically, velocity (v) can be expressed as v = Δx / Δt, where Δx represents the change in position and Δt represents the change in time.
How is velocity related to acceleration?
Velocity and acceleration are related because acceleration is the rate of change of velocity over time. An object can change its velocity by changing its speed, direction, or both, and this change is measured by acceleration.
