Mass, weight, acceleration, motion

SUMMARY

The discussion clarifies the relationship between mass, weight, and acceleration due to gravity. It establishes that weight (W) is directly proportional to mass (m) and the acceleration due to gravity (g), expressed in the formula W = mg. As one moves away from the Earth's center, gravitational acceleration decreases, resulting in a reduction of weight, despite mass remaining constant. The conversation also touches on the distinction between linear motion and rotary motion, indicating a need for further exploration of these concepts.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Familiarity with gravitational concepts
  • Basic knowledge of physics equations
  • Concept of linear and rotary motion
NEXT STEPS
  • Study the implications of Newton's second law (F = ma)
  • Explore gravitational acceleration variations with distance from Earth's center
  • Learn about the principles of linear motion versus rotary motion
  • Investigate the effects of mass on weight in different gravitational fields
USEFUL FOR

Students of physics, educators, and anyone seeking to understand the fundamental principles of mass, weight, and motion in relation to gravitational forces.

Hi,

I am confused with the basic blocks. These are meant to be known the way we know alphabets but I am not able to. I was just reading this fat physics book Serway Jewett but things are confusing

1. Mass is inversly proportional to acceleration, Ok i agreed then the book speaks about gravity acceleration still here things are cool understood then the author says the acceleration(gravity) is maximum at the center of the Earth and tends to decrease as it moves away ok...and he says the weight as well decreases WHY? Author said mass and acceleration are inversly proportional...and it also says weight is directly proportional to mass...I can visualise what he is saying and tends to be right but with equations na not understanding I feel as if I'm tangled with this. Someone entangle me out of this mystery. And also i would like to know the relation between the linear motion and rotary motion.


Kindly help me through this I would be very greatful

Thank you.

W=mg
Weight (N) = Mass (Kg) * acceleration due to gravity.
As you move further away from the Earth its gravitational field gets weeker so the weight would get less. I think that's what you were asking.
