B 11 Projectile Motion
Ball is projected horizontally, another dropped straight down
Later, horizontally lines drawn
Old PSSC – large white balls
B 12 Projectile Motion
Ball shot horizontally from crossbow as a target ball is dropped horizontally. Both originally aligned horizontal.
Old PSSC – large white balls
B 13 Projectile Motion
Ball shot at an upward angle from crossbow as a target ball is dropped horizontally.
Old PSSC – large white balls
B 14 Projectile Motion
Ping pong balls glued to plexiglas sheet at equal time intervals
Old PSSC – Professor Hume
B 15a Projectile Motion
Air table is tilted so pucks respond to “diluted gravity”.
One shot horizontal, one dropped.
Frame 3573
B 16 Frame of Reference
Flare dropped from airplane shown from a stationary position on the ground from side and head on and from within the airplane.
B 17 Frame of Reference
Flare fired from snowmobile
upward w/uniform horiz. motion
upward w/ no horizontal motion
upward w/uniform horiz. Motion
upward w/slow down and stop
upward w/increase in speed
B 21 Circular Motion
Vectors of displacement, velocity and acceleration of an object moving in a circle.
Old PSSC film
B 25 Circular Motion
Loop-the-loop park ride
wide angle view
view of accelerometer
from front of car
B 26 Circular Motion
Cork accelerometer accelerated
along straight line by a person
along a circular path on hood of car
B 27 Circular Motion
Focuses on relationship between period, force, mass, radius
uses dry ice puck
model airplane on string
B 28 Frame of Reference
Carnival ride – rotor – with floor dropping out
from stationary reference
from rotating frame reference
B 41 Planetary Motion
Copernican model of solar system is shown
Models of Sun and planets held by a person
Large scale model of the solar system set up along highway
B 42 Planetary Motion
Retrograde motion of with Earth, Sun and Mars
Works both from geocentric and heliocentric frame of reference.
B 43 Planetary Motion
Phases of the Moon
Artist’s rendering of Earth, moon and sun.
Still images showing relative positions of Earth and moon at each of four major lunar phases.
B 44 Planetary Motion
Tilt of the Earth
The angle of tilt of the earth’s axis
Tilted Earth with respect to its plane of revolution around Sun.
B 46 Planetary Motion
Foucault Pendulum
Full-scale pendulum swings for 30 minutes dropping sand.
Mock-up pendulum using a laboratory turntable. Dr Hume
