🤯 A visual physics lesson at 80 km/h Enthusiasts launched a person backward from a moving truck at the same speed the vehicle was traveling. The experiment clearly demonstrated how relative speed works.

Really interesting insight from Wayne Rooney on the type of speed that can sometimes get overlooked in football. You’ll often hear coaches say that top speed is overrated. That football is mostly about being quick over short distances. It’s a fair point - most sprints in football are relatively short. Approximately 2-4 secs, over 10-20m. So acceleration, anticipation and timing are hugely important. But Rooney’s point is equally true - give genuinely fast players 30–40m to open up and top end speed is a massive plus. The counter-attack goal against Arsenal in 09/10 is a brilliant example. Rooney starts from deep, sprints about 50m and has the ability to maintain his speed and get on the end of the pass. In the current Premier League era, that ability is particularly valuable in a game increasingly full of transitions. For both attackers and defenders. Manchester United used to publish their players’ top speeds, and Rooney was regularly right up there at or above 35 km/h. There’s another reason developing top speed matters too: speed reserve. Imagine two players: Player A max speed: 36 km/h Player B max speed: 31 km/h At 25 km/h, Player A is at 69% of their maximum speed. Player B is already at 81%. So the same absolute running speed represents a very different relative speed demand for each player. That’s just one more reason maximal speed matters beyond simply being able to win a foot race. Raise your ceiling and you increase the speed you have in reserve.
