Determine the gravitational force that you exert on another person

In summary, the conversation involved a request for help with a problem involving determining the gravitational force exerted by one person on another person 1.00 m away. The solution involved using the equation F=Gm1(m2)/r^2, and the final answer was calculated to be approximately 3.6 x 10^-7N.

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 [itex]3.55 \times 10^{-7}N=3.6 \times 10^{-7}N[/itex] to 1 dp.

1. How is gravitational force calculated?

Gravitational force is calculated using Newton's Law of Universal Gravitation, which states that the force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

2. What factors affect the gravitational force between two people?

The gravitational force between two people depends on their masses and the distance between them. The more massive the individuals are and the closer they are to each other, the greater the force.

3. How can we measure the gravitational force between two people?

The gravitational force between two people can be measured using a device called a gravitational force meter. It measures the force between two objects placed on opposite ends of a lever arm.

4. Does the gravitational force between two people change?

Yes, the gravitational force between two people changes as their masses or the distance between them changes. The force also changes if one or both individuals move relative to each other.

5. Can the gravitational force between two people be negative?

No, the gravitational force between two people cannot be negative. It is always an attractive force, meaning it pulls the two individuals towards each other. If the force is in the opposite direction, it is still considered positive but with a different sign.
