What is a 1st class lever?
100
This states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.

This is how far an object has moved in a given direction

What is distance?

This is why the Frosbury flop is a more efficient technique then the scissor jump.

This is the shortest distance between the initial point and the final point.

What is displacement?

This is the rate at which the body changes its velocity.

This zone shrinks or disappears during muscle contraction.
What is the H zone?
500

This is the axis for all free airborne rotations.

What is center of mass?

500

This principle relates the pressure of a fluid to its elevation and its speed.

What is Bernoulli's Principle?

This lever has the fulcrum lying at one end with the effort at the other and the load in the middle.
