A quick conception question Newtonian physics

Click For Summary
SUMMARY

The discussion centers on the concept of acceleration in Newtonian physics, specifically regarding objects of different masses. It is established that both a stone (1000kg) and a ball (1kg) experience the same acceleration of 9.81 m/s² when thrown upwards, assuming wind resistance is negligible. The argument clarifies that mass does not affect the acceleration due to gravity, which remains constant at 9.81 m/s² for all objects in free fall.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Basic knowledge of gravitational acceleration
  • Familiarity with the concept of free fall
  • Awareness of the effects of air resistance on motion
NEXT STEPS
  • Research the implications of Newton's second law of motion
  • Explore the concept of free fall and its equations
  • Study the effects of air resistance on different objects
  • Learn about gravitational acceleration variations on different celestial bodies
USEFUL FOR

Students of physics, educators teaching Newtonian mechanics, and anyone interested in understanding the principles of motion and gravity.

i was having an argument with my friend.

He claims that acceleration for object that is lighter, let say a stone (1000kg) and ball (1kg). If we were to throw them up in the sky with the same initial speed, their acceleration would always be 9.81ms^2 (depending on sign conventions). Am i right to say that?

My friend claims that the acceleration for the lighter object would be greater...

You're right. Your friend is wrong (assuming we're neglecting wind resistance).
