! Group assignments, 2-3 rides/4-6 students ! Common shared experience + use authentic data, photos, movies in examples How can teachers make use of amusement rides for STEM education? Safety – Normally not permitted to bring anything on rides CONTACT PARK BEFORE!.Field trip … practical considerations – Schedule – Transport – Money – Permits – Equipment.! Acceleration and rotations are absolute - can be measured within the system. ! Equivalence principle: Inertial (ma) and Gravitational (mg) mass ! Newtons's laws apply also to HUMAN bodies (Wellenflieger film) PraterTurm: D=14m, L=8m (and Himmelskibet, Tivoli, Kbh)ĭo all swings hang in the same angle? (Film ) Amusement rides offer illustrations of physics principles that are known to be difficult!

! Free fall in drop towers ! Centripetal forces in carousels ! Potential and kinetic energy in roller coastersĭifferent themes, designs and locations - same physics Acceleration? Luftikus, Martin Hopf et al Amusement rides in textbooks? The angle is about 45° corresponding to an acceleration of g. The angle of the string depends on the acceleration Start and landing of an airplane Measuring acceleration – and g-force (In horizontal motion)Ī g – acceleration of gravity - downwards a – centripetal acceleration – to the center ”g-force”:force (per kg) acting on the body How large acceleration?.Horizontal acceleration can be measured with a soft toy on a string.A FORCE is Example: 10 degrees – required to change from 0 to 50 km/h in 8s the velocity (speed and/or direction of motion).Teacher role: Preparations and follow up are essential Acceleration - in everyday language: Increase of speed (per second) and with measurements using toys, mobile phones and electronics Physics for many senses, in a variation of contexts, and authentic, enjoyable settingsĬombining the math and physics with the experience of eyes and your own body, Multiple senses The Amusement Park as a Science Center When you were at the highest point, the slinky was the shortest, which means that you were the lightest. When you went up, it was stretched out because there was so much speed. When you used the slinky in the Frog Hopper, you got to see how much you weighed.
