D1-36: AIR TABLE - CENTRIPETAL FORCE

• ID Code: D1-36
• Purpose: Show that centripetal force varies with angular velocity.
• Description: A string connects the rotating mass on the air table past a pulley to the spring scale. The centripetal force can be determined using the measured values of mass, rotational period and radius, then compared with that read from the spring scale. The period can be measured using the manual timer, if desired. Not available in small classrooms because it will not fit through a standard door.
