*1. Gravity*: This is the downward pull of the earth on the body. It is the most basic force in dance and affects the way dancers move and interact with the floor.
*2. Inertia*: This is the tendency of an object to resist changes in motion. In dance, inertia can be seen in the way dancers change from one movement to another.
*3. Momentum*: This is the product of the mass of an object and its velocity. In dance, momentum is created when dancers move with speed and force.
*4. Elasticity*: This is the ability of an object to return to its original shape after being deformed. In dance, elasticity can be seen in the way dancers stretch and contract their muscles to create movement.
