Help Sarah Design Momentum Experiment

AI Thread Summary
The discussion centers on designing a momentum experiment, with an emphasis on understanding the concept of momentum as the product of mass and velocity. Participants suggest consulting textbooks or online resources for foundational knowledge and encourage a problem-solving mindset, emphasizing that physics is accessible to everyone. Key steps include identifying independent and dependent variables, selecting appropriate materials, and setting up the experiment using a ramp to measure how different masses affect velocity. Data analysis will reveal the relationship between mass and velocity, illustrating momentum principles. The conversation concludes with encouragement to persevere through challenges in the experimental process.

im designing an experiment investigating momentum. but i don't know much about momentum and I am totally stuck regarding this silly experiment. HELP. pwease!??

i swear to god physics wasnt designed for womren. i wish id stuck to cooking and cleaning!

What are you supposed to investigate? If you need general information about momentum, consult a textbook or google.
 
, it's understandable that you may feel overwhelmed and frustrated with designing this experiment. However, I want to assure you that anyone, regardless of gender, can excel in physics. It's all about having a curious and problem-solving mindset.

First, let's define momentum. Momentum is the quantity of motion an object has, and it is calculated by multiplying an object's mass by its velocity.

Now, for your experiment, you can start by identifying the independent and dependent variables. The independent variable could be the mass of the object, and the dependent variable could be the velocity.

Next, think about what materials and equipment you will need to conduct the experiment. This could include objects of different masses, a ramp or inclined plane, and a timer to measure velocity.

You can then set up your experiment by placing the objects on the ramp and letting them roll down. Measure the time it takes for each object to reach the bottom and calculate their velocities.

Finally, you can analyze your data and see if there is a correlation between the mass and velocity of the objects, which would demonstrate the concept of momentum.

Remember, don't get discouraged if your first attempt doesn't go as planned. That's the beauty of experimentation, you can always make adjustments and try again. Don't give up, Sarah. I believe in you!
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
