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.

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.

• 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

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...")
