Just like in every other sport, you can apply physics to dancing. When we are jumping off the floor for a certain jump we are a.) using newton's third law b.) we are also using acceleration. To get ourselves off the ground we have to push off the floor, when we push down onto the floor the floor pushes back on us allowing us to leave the floor. When we are preparing to jump into the ground we have to run, we are applying acceleration to our bodies so that we are able to defy gravity's acceleration of 9.81 m/s^2. We can also apply Newton's first law to dancing, an object in motion stays in motion unless acted upon an outside force. when we perform certain turn sequences, which is when we continuously turn in circles, we have to have an outside force (a fellow dancer) stop us because our force is so great that we are not able to stop ourselves.
