John asks…What are the physics involved in surfing?Not so much the waves but the actual board.Nancy answers:The word of the day is friction. The wave is basically pushing the board although gravity plays a key role, but as far as the board is concerned, friction is the force working against you. Wax is applied to the bottom of surfboards to reduce the friction between the board and the water. The shape and size of the board will affect the manuverbility of the board and you could argue

Surfing For Physics Formulas For Velocity?

Chris asks…Physics Formulas - Velocity/Acceleration?What are each of these two formulas used for?

vf^2 - vi^2 = 2a(xf-xi)

I am confused.Nancy answers:This one...
Vf^2 - vi^2 = 2a(xf-xi)

If you re-arrange it, it's the more common (4th kinematics equation)

vf^2 = vi^2 + 2ad where d is the distance travelled under accel. Use this equation to solve most problems where time is not given.
