Amazing Physics Experiments

John Evans | Expert Vertical Jump Coach on Instagram: "The number one thing that moves the needle forward when it comes to acceleration mechanics is ACCELERATING. But there are a few things I’ve found can create context for this movement pattern. 1. A2s. These cue pushing the foot down and behind the hips in succession which can teach striking with a foot contact intentionally behind the body. 2. Imaging a Nike swoosh during accels. A friend of mine Patrick used this with myself and it always st

Galaxies on Instagram: "In a vacuum, all objects, regardless of their mass, fall at the same speed due to the absence of air resistance. This phenomenon is explained by Galileo’s principle of equivalence, which states that the acceleration due to gravity is the same for all objects. Hence, a bowling ball and a feather will fall at the same rate in a vacuum. On planets with no atmosphere, such as Mercury, the same principle applies. Without atmospheric drag, the bowling ball and the feather exper
