Interesting facts
The type of floor is particular to most dance companies. This changes the amount of friction, so does the type of shoes. The type of shoes can range from jazz shoes, no shoes, flat ballet shoes, and pointe shoes.
Topic
How do dancers use Newton's laws and air resistance to leap?
What forces, balanced and unbalanced, are at work in this sitiuation and how?
Before the person starts moving, they have a net force of 0, but they accelerate horizontally and put the most amount of force down to push themselves off of the ground (every action has an opposite and equal reaction). The acceleration will carry them sideways while the force from the ground pushes them up.
How are Newton's laws of motion and Universal Gravitation at play in this situation

(Newtons law)
1. The dancer should stay in the air forever but gravity pulls the dancer down
2. Forces, the accelertation of the jump depends on the amount of force the dancer puts into the floor when th take off.
3. When the dancer pushes off the ground, the opposite and equal forces push the dancer off the ground.
