Question

a student wants to know the gravitational force between a tree and a squirrel. they know the mass of the squirrel, the mass of the tree, and the gravitational constant, g. what else do they need to know? the age of the squirrel how tall the tree is the time of day the distance between them

Explanation:

To calculate the gravitational force between two objects, we use Newton's law of universal gravitation, which is given by the formula \( F = G\frac{m_1m_2}{r^2} \), where \( F \) is the gravitational force, \( G \) is the gravitational constant, \( m_1 \) and \( m_2 \) are the masses of the two objects, and \( r \) is the distance between their centers of mass. The problem states that the student knows the mass of the squirrel (\( m_1 \)), the mass of the tree (\( m_2 \)), and the gravitational constant (\( G \)). To find the gravitational force, the only remaining quantity needed from the formula is the distance (\( r \)) between the squirrel and the tree (specifically, the distance between their centers of mass). The age of the squirrel, the time of day, and how tall the tree is are not relevant to the gravitational force calculation as they do not appear in the formula for gravitational force.

Answer:

the distance between them
