Product Summary
This dual-purpose device can trigger the Smart Cart plunger or drop a ball from the side of a Smart Cart.
Trigger the Smart Cart plunger remotely for conservation of momentum experiments. The Trigger Dropper mounts in the bed of the Smart Cart, parallel to the cart, and is connected to the Smart Cart's accessory port. The plunger is released when the Trigger Dropper is activated either by pushing the button on the Trigger Dropper or remotely through Capstone or SPARKvue software.
Drop a ball from a moving Smart Cart to demonstrate projectile motion. The Trigger Dropper mounts in the bed of the Smart Cart, perpendicular to the cart. The ball is dropped when the Trigger Dropper is activated in the software. It can be activated after a specified time or when the cart reaches a specified position. When the ball hits the floor, where is the cart relative to the ball?
The Trigger Dropper can also be programmed in Blockly.
Applications
- Conservation of momentum in explosions
- Conservation of center of mass in a moving system undergoing an explosion
- Projectile motion of a ball released from a moving cart

Two stationary carts are against each other with the plunger cocked on one of the carts and the plunger is released so the carts explode apart. Momentum is conserved.
