Understanding the Law of Universal Gravitation
What Is the Law of Universal Gravitation?
The law of universal gravitation states that every mass attracts every other mass in the
universe 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. Formulated by
Sir Isaac Newton in 1687, this law explains the gravitational attraction that keeps planets
in orbit, causes objects to fall to the ground, and governs the motion of celestial bodies.
Mathematically, it is expressed as:
F = G (m₁ m₂) / r²
Where: - F is the magnitude of the gravitational force between the two objects - G is the
gravitational constant (~6.674×10⁻¹¹ N·(m/kg)²) - m₁ and m₂ are the masses of the
objects - r is the distance between the centers of the two masses
Significance of the Law
Understanding this law is crucial because it: - Explains planetary motion, satellite
trajectories, and tides - Serves as a foundation for classical mechanics - Helps predict the
behavior of objects in space and on Earth A law of universal gravitation worksheet

Sample Exercises from a Universal Gravitation Worksheet
To illustrate the depth and variety of questions, here are sample exercises often found in
such worksheets:
Exercise 1: Conceptual Understanding
Question: Explain why astronauts experience weightlessness in orbit, even though gravity
is still acting on them. Answer: Astronauts are in continuous free fall around Earth,
meaning they are moving forward at a speed that keeps them falling around the planet.
Since both they and their spacecraft are accelerating equally under gravity, they do not
feel weight; this condition is known as apparent weightlessness.
Exercise 2: Calculation
Question: Calculate the gravitational force between the Sun (\( 1.989 \times 10^{30} \)
kg) and Earth (\( 5.972 \times 10^{24} \) kg), given that the average distance between
them is about 149.6 million km. Solution: Convert distance to meters: \( 149.6 \times
10^{6} \text{ km} = 1.496 \times 10^{11} \text{ m} \). Apply the formula: \[ F = G
\frac{m_{Sun} \times m_{Earth}}{r^2} \] Plugging in values: \[ F = 6.674 \times
10^{-11} \times \frac{(1.989 \times 10^{30}) \times (5.972 \times 10^{24})}{(1.496
\times 10^{11})^2} \] Calculating yields approximately \( 3.54 \times 10^{22} \)
Newtons.
