Calculate the force of gravity between a human child (mass = 38 kg) and the planet Mars (mass = 6.4 1023 kg), when Mars is at its closest to Earth (distance = 8. 1010 m).
To calculate the force of gravity between two objects, we can use the following formula:
F = (G * m1 * m2) / r^2
Where:
F is the force of gravity
G is the gravitational constant (6.67430 × 10^-11 N m^2/kg^2)
m1 and m2 are the masses of the two objects
r is the distance between the centers of the two objects
In this case, the mass of the human child is 38 kg, the mass of Mars is 6.4 * 10^23 kg, and the distance between them is 8 * 10^10 m.
Let's plug in these values into the formula:
F = (6.67430 × 10^-11 N m^2/kg^2) * (38 kg) * (6.4 * 10^23 kg) / (8 * 10^10 m)^2
Now we can calculate the force.
