To calculate velocity, you need to divide the displacement by the time taken. The formula is v = d/t, where v represents velocity, d is displacement (the distance between the starting and end points, considering direction), and t is the time taken. This calculation will give you the average velocity. If you have velocity varying across the time, you might need to consider differential calculus for instant velocity. Remember, velocity is a vector quantity, so it includes both magnitude and direction.
FAQs & Answers
- What is the formula for velocity? The formula for velocity is v = d/t, where v is velocity, d is displacement, and t is the time taken.
- How is velocity different from speed? Velocity is a vector quantity that includes both magnitude and direction, whereas speed is a scalar quantity that only measures magnitude.
- What is instant velocity? Instant velocity refers to the velocity of an object at a specific moment in time, often calculated using differential calculus when velocity varies.
- Why is displacement used instead of distance in velocity? Displacement considers the direction between start and end points, making velocity a vector quantity, unlike distance which measures only the total length traveled.
