Force and acceleration is what moves an object and how fast it is moving. In our project, the physics of yoga, the main force acting on us is gravity and using balance to stay in the poses. Newtons first law is an object in motion stays in motion meaning if an object is moving and there is no opposing force on it it will stay moving. His second law is force = mass X acceleration. This means that if you push an object to the left it will go to the left and if you push it twice as hard it will move twice as fast. Newtons third law is that for every action there is an equal and opposite reaction. This means if you push on a wall the wall is pushing back just as hard.
Speed is the rate of motion and velocity is the speed in any given direction.
Velocity = distance / time
momentum = mass X velocity
