SUMMARY

The discussion focuses on the forces acting on a cyclist reaching maximum speed, specifically addressing the balance between pedaling force and resistive forces, including friction and air resistance. When a cyclist stops accelerating, they achieve terminal velocity, where the pedaling force equals the sum of resistive forces. This equilibrium results in a constant velocity, as the resistive forces increase with speed until they match the applied force from pedaling.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Basic knowledge of forces, including friction and air resistance
  • Familiarity with the concept of terminal velocity
  • Basic physics of cycling dynamics
NEXT STEPS
  • Research the impact of aerodynamic drag on cycling speed
  • Study the principles of force balance in motion
  • Explore advanced models of cycling dynamics and energy expenditure
  • Learn about the effects of different bike geometries on speed and resistance
USEFUL FOR

Cyclists, physics students, sports scientists, and anyone interested in understanding the mechanics of cycling performance and speed optimization.

if a person pedals as fast as he can on a bike, and stops accelerating, and his speeds reaches maximum value. how do i explain it in terms of forces acting. can someone please provide me wth a model answer thx. ( by the way i know he reaches terminal velocity, but i don't know how to explain it in forces)
 
Physics news on Phys.org
can i say the force exterted equals the frictional force, and so she reaches a constant velocity? i noe i am liek retarded: anyway please help me asap=(
 
Yes that's basically it, except friction here includes the air resistance. Resistive forces get bigger as the speed increases and eventually reach the point where they balance the pedalling force, so no further acceleration
