240 views

Speed in physics is expressed as the distance traveled per unit of time. The formula for speed is speed = distance / time. Standard units include meters per second (m/s) and kilometers per hour (km/h).

FAQs & Answers

  1. What is the formula for speed in physics? The formula for speed is speed = distance divided by time (speed = distance / time).
  2. What units are used to express speed? Speed is commonly expressed in meters per second (m/s) and kilometers per hour (km/h).
  3. How does speed differ from velocity in physics? Speed is a scalar quantity representing how fast an object moves, while velocity is a vector that includes both speed and direction.
  4. How do you calculate speed if distance and time are known? Speed can be calculated by dividing the total distance traveled by the time taken to travel that distance.
