AI Thread Summary
Identifying types of forces involves understanding the various influences acting on objects, such as gravity, friction, and air resistance. In the example of a rock falling through the air, gravity pulls the rock downward while air resistance opposes its motion. The discussion emphasizes the importance of recognizing these forces to grasp basic physics concepts. Additionally, the conversation highlights the necessity of being specific when identifying forces in different scenarios. Understanding these principles is crucial for science students studying mechanics.

Hm... My science study guide tells me to identify types of forces. What do they mean? Can you help me identify forces?:confused:
 
Physics news on Phys.org
Can you be more specific please?
 
um... their example is : what forces are being applied to a rock falling through the air?

Well there are couple you may think of on top of your head.

For instance, we don't float in the air while we are on earth. This means that there is "what" acting on us?
 
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...
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 .
