  • You feel gravity when you jump with your bike and come down.
    True
  • The force that keeps you moving in a circle is called centripetal force.
    True
  • Inertia is the tendency of your body to keep moving when the coaster stops.
    True
  • Safety bars keep you in place when the roller coaster stops.
    True
  • You feel friction when you use the brakes to stop the bike.
    True
  • When the roller coaster stops quickly, your body wants to stop too.
    False. When the roller coaster stops quickly, your body wants to keep moving. This is called inertia.
  • Gravity pulls the roller coaster down the hill quickly.
    True
  • At the top of the loop, you are high in the sky and upside down.
    True
  • You need to pull down the safety bar before the roller coaster ride starts.
    True
  • The roller coaster uses friction to stop.
    True
  • You can experience forces by riding a bicycle or a roller coaster.
    True
  • Some people feel dizzy or sick on roller coasters because the forces change.
    True
  • You feel very light when the roller coaster moves quickly downhill.
    True
  • You feel light when you go quickly up the loop-the-loop.
    False. You feel heavy when you go quickly up the loop-the-loop.
  • We experience friction, centripetal force, and gravity in everyday life.
    True
  • Only roller coasters let you feel the forces of gravity, friction, and centripetal force.
    False. You experience these forces in daily life, not just on roller coasters.
  • The roller coaster goes slowly up a steep hill.
    True
  • You don’t fall out of your seat because your body holds you in.
    False. You don’t fall out because centripetal force and the speed of the car keep you in your seat.
  • You feel centripetal force when you turn your bike.
    True
  • Gravity pulls you down when you are going through the loop.
