Situation: Riding a Bike

Where does this situation happen? This situation can occur outside, such as on a bike path, at a park, or in a neighborhood.

What are the forces acting on the object?

  1. Gravity - Pulls the rider and the bike down towards the ground.
  2. Normal Force - The ground exerts an upward force on the bike and rider, counteracting the force of gravity.
  3. Friction - There are two types of friction at play:
    • Rolling Friction - Between the bike tires and the ground, which allows the bike to move without slipping.
    • Air Resistance (Drag) - Opposes the motion of the bike as it moves through the air.
  4. Pedaling Force - The rider pushes down on the pedals, applying a force that propels the bike forward.
  5. Inclination Force - If riding on an incline, there's a component of gravitational force acting along the slope, which affects how easily the rider can ascend or descend.
