As the Winter Olympics draws to a close this weekend, scientist and Newcastle Graduate Ambassador, Ashleigh, takes us through some of the most interesting sports science stories of the games.
Science is becoming more and more important in sport as our understanding of sport and technology improves. The 2018 PyeongChang Winter Olympics have highlighted the importance and more evident involvement of science in sport, Brian Cox even narrated the opening montage of the BBC’s sports coverage.
Here’s 10 of our favourite sport and exercise science stories from the 2018 PyeongChang Winter Olympic games…
- One big story recently has been the Russian doping scandal, banning the Russian team from competing. Scientific America look at how doping is carried out in the Olympics.
Some Russian athletes have been able to compete representing Olympic Athletes from Russia rather than The Russian team.
- Although after bans are completed most athletes usually return to competing, this blog post describes how drugs such as steroids can have a lasting effect on athletes even after athletes stop using them.
- Why are so many people game to throw themselves off the side of a mountain standing on couple of skinny planks of wood? This blog dives into the attraction of the adrenaline pumping winter sports.
Eddie the Eagle became an unlikely British hero after signing up to the 1988 Winter Olympics to compete in the Ski Jump (without much success) despite his limited experience!
- Winter Olympics are seen as some of the more dangerous sports but statistics show that the fairly leisurely sport of curling has more recorded injuries at the Olympics than Ski Jumping!
- Protective helmets are a common feature in the games but the high levels of injury also mean that more time and money is being spent on athlete safety. We could even see some athletes sporting airbags at the games!
- Meteorologists predicted this was going to be the coldest Olympics yet! The new technology even stretched to the outfits the teams would be wearing, with electric blanket style coats to stay warm!
- Great Britain’s clothing even caused a bit of a “cheating” scandal. Their suits had been designed to reduce drag by adding ridges, giving similar aerodynamics to a golf ball. Luckily it was decided that the suit was allowed and Team GB went on to win a Gold and Bronze medal in the women’s Skeleton event.
- If you’ve ever been ice skating and had to cling onto the side of the wall, you may think figure skating looks impossible. This article describes how practicing figure skating can rewire the brain to overcome that fear of falling flat on your face.
- The US winter Olympic team have also been training their brains, using brain stimulation and virtual reality equipment. Sports scientists believe this will optimise the training gains.
- And finally, it turns out everyone’s favourite winter Olympic sport is also a marvel of physics!

Ever wondered what makes the perfect pancake flip? Let’s look at the physics behind getting those pancakes flying through the air.
If we start with our pancake at rest in the pan, the pancake will not move unless a force is put upon it. This is Newton’s first law of motion, an object at rest will remain at rest unless acted on by an outside force. In order to launch our pancake in the air we therefore apply a force to it. We can use an energy equation to work out the velocity (speed with a direction) needed to launch the pancake into the air as follows:
m – Mass of the pancake
g – Gravitational field of the earth 9.81 metres per second
h – Height of pancake flip
v – Launch velocity
We now need Newton’s second law of motion to find out how fast we need to flip the pancake. Newton’s second law of motion states that a force, acting on an object, will change its velocity by changing either its speed and/or its direction. In the case of our pancake the flipping force will increase the velocity and send the pancake in an upwards direction. The energy equation can be rearrange to give the pancake launch velocity:
If we want to flip the pancake 1 metre in the air we need a launch velocity of 4.4 metres per second. If our launch velocity is over 6 metres per second however, our pancake will get stuck to the ceiling! We also have to be fast to catch the pancake as it falls back down or we could be left with pancake on the floor! For a flip of 1 metre we only have 0.9 of a second to catch our pancake. We can calculate the air time (t) of our pancake using the following equation:So when you are flipping your pancakes today think of all the wonderful physics behind that perfect flip!
Today, 11th February, is the United Nation’s International Day of Women and Girls in Science. Over the past few years there has been a global push to engage more women and girls in science in order to reduce the gender imbalance within the STEM industries. Whilst progress has been made, still more needs to be done. Our fact file below highlights the existing issues with regards to gender representation within science and engineering.
Collectively, we need to work together to inspire young women to pursue careers in science. At Newcastle University we have a fantastic team of outreach officers who’s job it is to encourage young people to engage with STEM. Take a look at the different workshops they offer here.
