Gravitational Force

The gravitational force is the force of attraction between two objects with mass. This force is what makes objects fall to the ground and keeps the planets in orbit around the sun.

Newton's Law of Universal Gravitation

According to Newton's law of universal gravitation, every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

The formula for the gravitational force between two objects is given by:

F = G * (m1 * m2) / r^2

Where:

F is the gravitational force
G is the gravitational constant (6.67430 × 10^-11 m^3 kg^-1 s^-2)
m1 and m2 are the masses of the two objects
r is the distance between the centers of the two objects

Study Guide

Here are some key points to remember when studying gravitational force:

Understand the concept of gravitational force as the force of attraction between objects with mass.
Memorize Newton's law of universal gravitation and be able to apply the formula to solve problems.
Understand the role of the gravitational constant in determining the strength of the gravitational force.
Practice calculating gravitational force between different objects at varying distances.
Understand the relationship between gravitational force and the motion of celestial bodies such as planets and moons.

Remember to review these concepts and practice solving problems to reinforce your understanding of gravitational force.

Concepts of Physical Science (SB1, SB2, SB3, SB4)

The student demonstrates an understanding of the interactions between matter and energy and the effects of these interactions on systems by researching applications of nuclear reactions in which a small amount of matter is converted directly into a huge amount of energy (i.e., E=MC2). (L)
