Air Rockets can be a fun way of investigating forces. When a air rocket is launched compressed air
forces the cardboard rocket off the launcher and up into the air.
• Name the forces acting on the rocket at the top of it's flight.
. Are the forces at the top of the flight balenced or unbalenced?
• Describe how the size and direction of the air resistance force changes during flight, an state
the definition of friction.
