# Calculating Gravitational Force: Baby vs Mars

• LoveKnowledge
In summary: It stands for brackets, exponents, division, multiplication, addition, and subtraction. This means that in order to solve a math problem, you should first simplify any expressions within brackets, then work with any exponents, followed by division and multiplication, and finally addition and subtraction. So for this problem, you would first plug in the values for mass and distance, then simplify the equation using bedmas to find the force of gravity between the baby and obstetrician. Then, you would plug in the values for Mars and its distance from the baby to find the gravitational force between the baby and Mars. From there, you can compare the two forces to determine which exerts more force on the baby and

1. Calculate the force of gravity between a newborn baby of mass 3 kg and the obstetrician of mass 100 kg, who is 0.5 m from the baby. Which exerts more gravitational force on he baby, Mars or the obstetrician? By how much?

2. F = G m1m2/d2

3. Fg = (Gm1 Gm2) /d^2 =Fg= g ( 3.00 kg)(100.0 kg)/0.5m^2 =Fg= (6.67 E -11 N*m2/kg2)( 3.00 kg)(100.00 kg)/0.5m^2

I don't seem to know how to do the math following plugging the equations together :(

You're notation is a bit messy, I think, you have an extra G appearing and you're switching between g and G for the gravitational constant.

You've inserted the numbers right, though. Now just put the expression into a calculator to get a value for the force.

Then you'll need to look up the mass of Mars and how far away it is and replace 100kg with the mass of Mars and 0.5m with the distance to Mars. It's worth noting that the distance to Mars will vary because both Earth and Mars are moving. Maybe you could take the average distance or the maximum distance or the minimum distance, that's up to you, really.

## 1. How can I calculate the gravitational force between a baby and Mars?

To calculate the gravitational force between a baby and Mars, we can use the equation F = G(m1m2)/r^2, where G is the gravitational constant (6.67 x 10^-11 N*m^2/kg^2), m1 and m2 are the masses of the two objects, and r is the distance between them.

## 2. What is the mass of a baby and Mars that should be used in the calculation?

The mass of a baby can vary, but for the sake of this calculation, we can use an average mass of 7.5 kg. The mass of Mars is approximately 6.39 x 10^23 kg. These values can be substituted into the equation to calculate the gravitational force.

## 3. How far apart should the baby and Mars be for the calculation?

The distance between the baby and Mars should be measured in meters. The average distance between Earth and Mars is approximately 225 million kilometers, or 225 x 10^9 meters. This value can also be converted to meters by multiplying by 1 billion.

## 4. What is the gravitational force between a baby and Mars compared to the force between a baby and Earth?

The gravitational force between a baby and Mars will be significantly less than the force between a baby and Earth. This is because Mars has a much smaller mass than Earth, and the force of gravity is directly proportional to the masses of the objects involved.

## 5. How does the gravitational force between a baby and Mars affect the baby's weight?

The gravitational force between a baby and Mars would be significantly less than the force between a baby and Earth, so the baby's weight on Mars would also be significantly less. The baby would feel lighter and may even be able to jump higher on Mars due to the lower gravity.
