I'm actually doing a project but I don't know how easy it will be to describe it. It involves two weights, both attatched to the same string through the center of a flat surface so one weight is directly on the surface, and the other is dangling below. What the intention is, is that when the weight on the surface is flicked, the one dangling does not bobble or move. Therefore the dangling weight cannot be too light. We need to use everyday items, but I'm just not too sure what the correct weights would be. I understand completely if no one can help me, as this isn't really a question. But thanks if anyone can.

It seems like you are working on an interesting project involving weights and the motion of a dangling weight when another weight on a flat surface is flicked. To find suitable weights, you will need to consider the physics principles of balance and conservation of momentum.

Here's a step-by-step approach to help you determine the correct weights for your project:

1. Define the variables: Let's label the weight on the surface as "Weight A" and the dangling weight as "Weight B." To simplify calculations, it's helpful to assign numerical values to some variables such as the mass of Weight A (mA in kg) and the mass of Weight B (mB in kg).

2. Determine the initial conditions: Consider the initial position and initial velocities of both weights. Since Weight A will be flicked, it will have an initial velocity. Weight B will initially be at rest. You can assume that the string connecting both weights does not have any significant mass or affect the motion.

3. Apply conservation of momentum: When Weight A is flicked, it will gain momentum. According to the principle of conservation of momentum, this momentum must be transferred to Weight B. Therefore, the total momentum before flicking should be equal to the total momentum after flicking.

Mathematically, this can be expressed as:
(mA * vA)_initial + (mB * vB)_initial = (mA * vA)_final + (mB * vB)_final,

where (mA * vA) represents the momentum of Weight A and (mB * vB) represents the momentum of Weight B.

4. Consider the motion of Weight B: Since you want Weight B not to bobble or move, its final velocity (vB_final) should ideally be close to or equal to zero. This means the momentum transferred to Weight B must be dissipated, creating a very small or negligible velocity change.

5. Experiment and iterate: Given the constraints of using everyday items, you can start with reasonable masses for Weight A and Weight B. Try different combinations and observe the motion. Adjust the weights as needed until you achieve the desired outcome of Weight B not moving significantly when Weight A is flicked.

Remember, this project involves experimentation and trial and error. By applying the principles of balance and conservation of momentum, you can find suitable weights for your project.
