SUMMARY

The discussion focuses on understanding the acceleration of two cardboard objects with identical mass (0.1 kg) but differing air resistance forces (0.5 N and 0.1 N). It concludes that the object experiencing the lower air resistance (0.1 N) will have a greater acceleration while falling, as air resistance opposes gravitational force. The conversation emphasizes the importance of visualizing concepts through experimentation to grasp the relationship between air resistance and surface area effectively.

PREREQUISITES
  • Basic understanding of Newton's laws of motion
  • Familiarity with the concept of air resistance
  • Knowledge of force diagrams
  • Basic experimental design skills
NEXT STEPS
  • Conduct a simple experiment to observe the effects of air resistance on different objects
  • Study Newton's second law of motion in detail
  • Learn about the factors affecting air resistance, including surface area and shape
  • Explore the concept of terminal velocity and its relation to falling objects
USEFUL FOR

Students studying physics, educators teaching concepts of motion and forces, and anyone interested in understanding the effects of air resistance on falling objects.

hi,
I have a problem that, conceptually, i do not get. I've looked through my physics book, and I still can't grasp it. If you just explain this one, i think ill catch on to the rest of the problems.

A cardboard ball has a mass of 0.1 kg. A sheet of identical carboard has the same mass, 0.1kg. The two pieces of carboard are allowed to fall. One of them feels an air resistance force of 0.5 N. The other feels an air resistance force of 0.1 N. Which force goes with which object? Which object has a greater acceleration while falling? (Try to answer without doing any math.)

Thanks! :biggrin:

What do you know about air resistance's relationship with the size of the object (more importantly, the incident surface area). When you drop a ball and a piece of paper, which one is hindered more by air resistance?

For the second question, a force diagram should give you the answer.
 
if you can't conceptualize the problem, why don't you try to actually do it experimentally? It's not very hard to make this experiment in your kitchen and it might just give you the visualization you need for the next questions.
