Project Overview and PurposeProject Overview and Purpose

In this project, we made a device that will pour a glass of In this project, we made a device that will pour a glass of water into another cup using four distinct steps that water into another cup using four distinct steps that shows the use of conservation of momentum, shows the use of conservation of momentum, gravitational potential, and kinetic energy.gravitational potential, and kinetic energy.

Energy ConservationsEnergy Conservations

Our project consists of three types of conservations: Our project consists of three types of conservations: momentum, gravitational potential, and kinetic. momentum, gravitational potential, and kinetic.

In step one we have gravitational potential energy In step one we have gravitational potential energy transferring into kinetic energy.transferring into kinetic energy.

In step two, the kinetic energy increases and the In step two, the kinetic energy increases and the potential energy decreases as the car travels down the potential energy decreases as the car travels down the track.track.

In step three, the kinetic energy is transferred to the In step three, the kinetic energy is transferred to the bottle through conservation of momentum.bottle through conservation of momentum.

In step four, the potential energy of the water in the In step four, the potential energy of the water in the bottle is transferred to kinetic energy as it travels down bottle is transferred to kinetic energy as it travels down the tube into the cup.the tube into the cup.

Step OneStep One

Two erasers are attached Two erasers are attached to a string which is able to to a string which is able to swing from a pendulum. swing from a pendulum. The erasers are held from The erasers are held from a certain distance from a certain distance from the top of the box. It is the top of the box. It is then let go and all of it’s then let go and all of it’s momentum is transferred momentum is transferred to the toy car sitting on to the toy car sitting on the top of the track.the top of the track.

Step TwoStep Two

Once the car is hit by Once the car is hit by the erasers, it the erasers, it accelerates as it goes accelerates as it goes down the track due to down the track due to the slope, thus all of the slope, thus all of its stored potential its stored potential energy is then energy is then transferred to kinetic transferred to kinetic energy as it reaches energy as it reaches the bottom of the the bottom of the track.track.

Step ThreeStep Three At the bottom of the track, At the bottom of the track,

there is an open bottle filled there is an open bottle filled halfway with water that is halfway with water that is waiting to be hit by the car. waiting to be hit by the car. The car will strike the top of The car will strike the top of the bottle, which will then the bottle, which will then make it tip over and dump it’s make it tip over and dump it’s water into the beer bong water into the beer bong secured to the edged of the secured to the edged of the box.box.

Step FourStep Four

In this final step, the In this final step, the water will travel down water will travel down the tube into an the tube into an empty cup sitting on empty cup sitting on the floor.the floor.

ConclusionConclusion

We found our project successful for We found our project successful for transferring water from a bottle to a cup. transferring water from a bottle to a cup.

Our three different conservations were Our three different conservations were momentum, gravitational potential, and momentum, gravitational potential, and kinetic energy.kinetic energy.
