Parachute Investigation

VelocityDefinition: • The constant maximum velocity reached by a

body falling through the atmosphere under the attraction of gravity

Stokes' law• F is the frictional force • r is the particle radius • µ is the fluid viscosity• v is the particles speed

Stokes law

mg = 6 πηr vT6 πηr vT

mg

When the parachute is falling it will eventually reach terminal velocity. When it reaches terminal velocity it means that there is the same amount of weight on the parachute as there is on his body.
