Box 4: Making things move Explain the relationship between the python code
force = -G*sun. M*earth. M*R/magR**3
and the equation
F⃗ = −GmSmE Rˆ . R2
Hint: starting with the vector R⃗ how can we find the unit vector Rˆ which points in the direction of R⃗? Remember that we use in python we use ** for exponentiation so that magR**3 means (magR)3.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

mass:

d) physical means can be used to separate the components of air.

the correct answer is "inertia"
