Speed is a measure of How fast something moves With Distance over Time The formula we use Then, there’s Velocity That’s a Vector Quantity Adding onto Speed Directionality [Break] When we want to work out Speed on average Distance we require Of journey entire [Break] Then the time duration To our destination Divide the first by the next Nothing too complex! [Break] So let’s say there’s a ship That sets sail on a trip And after one full day It’s 48 miles away [Break] Take the miles, 48 Divide by twenty four Makes two miles per hour Neither less nor more [Break] Now, for Velocity A compass we will need To know ship direction, and Combine it with the Speed [Break] So if the ship was sailing East We’d write the Velocity As two miles per hour East That’s degrees ninety! [Break] Speed is a measure of How fast something moves With Distance over Time The formula we use Then, there’s Velocity That’s a Vector Quantity Adding onto Speed Directionality [Break] But Speed in the moment Termed “Instantaneous” Those who drive must know So that they may slow [Break] When they go too fast And there’s a tool for that To warn them of danger: The Spee-dommeter [Break] But, in journey ordinary Such a Speed will vary As with runners in a race Over time they’ll change pace [Break] Faster as they near to win Slower as fatigue kicks in That’s Acceleration And Deceleration [Break] Speed is a measure of How fast something moves With Distance over Time The formula we use Then, there’s Velocity That’s a Vector Quantity Adding onto Speed Directionality
