Side B

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 15b Projectile Motion

Determine range of angle vs angle of shot.

Frame 3914

B 15c Projectile Motion

Frame 4385

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 22 Circular Motion
