The Longest Ride

The Longest Ride is a romantic film based on one of Nicholas Spark's novel. Well, it is romantic so you must have been wondering where will the physics fits in. 

In the movie, the hero, Luke is a professional bull rider. Bull riding is a rodeo sport that involves a rider getting on a bull and attempting to stay mounted while the animal attempts to buck off the rider. The forces that the bull exerts on the rider is the same as the force the rider exerts back on the bull. The difference is that the bull is about ten times the size of the rider, so that's a ten times the acceleration. He experienced G-force during the ride. 

There's also gravity effect when Luke was thrown off the bull. As the bull spins, we can see it accelerated and there was torque involved. Luke could only use one hand to stay on the bull. So he balances himself by staying at the center of the bull and with the help of his free hand. It is important for him to lean back when the bull dives forward to counter the momentum and then rhythmically shift his weight the opposite way when the bull tips up in the front.
