• 12:38, 4 April 2022 Physdemo talk contribs created page Inertia Pull (Created page with "{{NewDemo|subject=Mechanics|topic=Newton's Laws|file1=Inertia_Pull.png|file2=Inertia_Pull_2.png}} A 500g mass is hung by a thin string and a similar piece is attached below the mass. When a sharp downward force is applied to the lower string it breaks. This can be done by grabbing the rod at the bottom and pulling the whole set up until there is no bend in the string, but no harder. Then pull hard and quickly. When the force is gradually applied to the lower string the...")

• 10:39, 4 April 2022 Physdemo talk contribs created page Inertia of Concrete Block (Created page with "{{NewDemo|subject=Mechanics|topic=Newton's Laws|file1=Inertia_of_Concrete_Block.gif}} The inertia of the heavy concrete block absorbs the momentum of the hammer blow. The concrete breaks as it absorbs this impulse. PUT A GLOVE ON THE HAND UNDER THE BLOCK-- This will help to prevents cuts from the rough surface of the block. Don't be shy, no one has been hurt yet.

• 10:33, 4 April 2022 Physdemo talk contribs created page Hoop and Pen (Created page with "{{NewDemo|subject=Mechanics|topic=Newton's Laws|file1=Hoop_and_Pen.gif}} Balance a pen on top of a hoop which sits on top of a narrow necked bottle. Quickly pull the hoop away and the pen will fall into the bottle. A variation of the table cloth and china trick, this is a much easier demo but take note, it does require a practiced hand. '''Location:''' * Sh. A-3")

• 11:28, 1 April 2022 Physdemo talk contribs created page Shoot Garfield (Created page with "{{NewDemo|subject=Mechanics|topic=Kinematics|file1=garfield.jpeg}} A blast of pressurized air shoots a dart towards the target. As it leaves the barrel it passes through a photogate which cuts power to an electromagnet holding the target. The dart hits the target as it falls showing that both have fallen at the same rate. This is also available on video tape and can be shown in slow motion. (Garfield has been substituted for the monkey to cut down controversy.) '''Loca...") Tag: Visual edit: Switched
• 11:26, 1 April 2022 Physdemo talk contribs created page Projectile Gun (Created page with "{{NewDemo|subject=Mechanics|topic=Kinematics|file1=Projectile_gun_real}} A spring loaded ball launcher.

Both balls hit the floor at the same time. Demo should be done over a hard surface so there is a simultaneous sound as the balls hit the floor at the same time. '''Location:''' * Sh. B-3") Tag: Visual edit: Switched

A trigger Bracket mounts onto the cart track. The bracket blocks a photogate which launches the ball vertically. The cart travels through a tunnel and the ball falls back into the cart on the other side of the tunnel. This demonstrates the independence of vertical and horizontal motion. 12/1/2021 '''Location''' *Howitz...") Tag: Visual edit: Switched

Work extremely well with the sonic ranger motion detector. Also nice for qualitative momentum conservation demonstrations. Neodymium magnets are mounted on one end of the carts for elastic collisions. Velcro is mounted on the opposite ends and used for inelastic collisions. A spring loaded plunger is on each cart a...")
