Document Summary

Jan 16 mechanics, forces, vectors and fbd s. Know how to indicate the external forces acting on a body. Standing vertical jump y a typical ground reaction force curve for a standing vertical jump is shown below y when the person dips down, the grf decreases. At this point, the lowest amount of force is being applied on the jumper and the lowest amount of force is being applied on the ground y when the jumper pushes off the ground, the max grf occurs. This is the force that causes you to jump y when the jumper takes off, the grf is 0. Contact forces y wherever a defined system is in contact with other bodies forces are applied if the system is the rider, at every point of contact between the rider and the bike, there y are forces.
