Determine the gravitational force that you exert on another person

Click For Summary
SUMMARY

The gravitational force exerted between two point masses, each weighing 73.0 kg and separated by a distance of 1.00 m, is calculated using Newton's law of universal gravitation. The formula used is F = Gm1(m2)/r^2, where G is the gravitational constant (6.67 x 10^-11 Nm²/kg²). The calculated force is approximately 3.5 x 10^-7 N, which can be rounded to 3.6 x 10^-7 N when considering significant figures.

PREREQUISITES
  • Understanding of Newton's law of universal gravitation
  • Familiarity with the gravitational constant (G)
  • Basic algebra for manipulating equations
  • Knowledge of significant figures in scientific calculations
NEXT STEPS
  • Study the implications of gravitational force in real-world applications
  • Learn about gravitational force calculations in varying distances
  • Explore the concept of gravitational fields and their effects
  • Investigate the differences between point masses and extended bodies in gravitational calculations
USEFUL FOR

Students in physics, educators teaching gravitational concepts, and anyone interested in understanding the fundamentals of gravitational interactions between masses.

Hi everyone,

Could someone please help me with this problem?

Homework Statement


Determine the gravitational foce that you exert on another persona 1.00 m away. Assume that you and the other person are point masses of 73.0 kg each.


Homework Equations


F=Gm1(m2)/r^2


The Attempt at a Solution



F=(6.67X10^-11Nm^2/kg)(73.kg)(73.0kg)/1m=3.5X10^-7N

Thank you very much

Thank you very much

Should be correct...although just remember that 3.55 \times 10^{-7}N=3.6 \times 10^{-7}N to 1 dp.
 
Thank you very much
