This project demonstrates the law of conservation of momentum through a series of collision experiments. You'll measure velocities and analyze results, making physics fun and interactive! Great for middle school science fairs.
If two objects collide, then the total momentum before the collision will equal the total momentum after the collision.

Measure the mass of each marble using the scale.
Set the wooden platform on a flat surface.
Roll one marble towards the other and observe the collision.
Use the stopwatch to time the distance traveled by each marble post-collision.
Record the velocities before and after the collision.
Calculate the momentum for each marble.
Analyze the total momentum before and after the collision.
Repeat with different initial velocities.
The total momentum calculated before the collision should equal the total momentum after the collision, demonstrating the conservation of momentum.

Ensure the area is clear to prevent any accidents during collisions. Handle marbles carefully to avoid slipping.
Include diagrams to illustrate momentum calculations.
Use charts to display your recorded data.
Explain the physics concepts clearly on your display.
Practice your presentation to be concise.
