To calculate speed in physics, use the formula: speed = distance / time. Measure the distance traveled and the time it took. For example, if a car travels 100 meters in 5 seconds, its speed is 20 meters per second (100m / 5s = 20m/s). Ensure to use consistent units for accurate results.

FAQs & Answers

  1. What is the formula to calculate speed in physics? The formula to calculate speed is speed = distance divided by time.
  2. How do you measure speed accurately? Measure the total distance traveled and the time taken using consistent units, then divide distance by time.
  3. What units are used for speed? Common units of speed include meters per second (m/s) and kilometers per hour (km/h).
  4. What is the difference between speed and velocity? Speed is a scalar quantity that measures how fast an object is moving, while velocity is a vector quantity which also includes direction.
