This page continues with more complex universal gravitation practice problems with solutions. It presents two additional problems that require students to apply their knowledge of the gravitational force equation in different ways.
Problem 8 asks students to find the distance between two spherical objects given their masses and the gravitational force between them. This problem introduces the concept of solving for distance when force is known, using the equation r = √.
Example: The solution shows that for objects with masses 8.1 x 10² kg and 4.5 x 10³ kg experiencing a gravitational force of 1.9 x 10⁻³ N, the distance between their centers is 113.119 m.
Problem 9 requires students to determine the mass of one object given the distance between two objects, the gravitational force, and the mass of the other object. This problem utilizes the equation m₁ = r²F/(Gm₂) to solve for mass.
Highlight: These problems demonstrate how the universal gravitation equation can be rearranged to solve for different variables, enhancing students' problem-solving skills.
By working through these problems, students learn how to find gravitational force with mass and distance, as well as how to calculate other variables when given partial information. This page reinforces the versatility of the gravitational force formula and its applications in various scenarios.

The final page of the practice set presents a comprehensive problem that explores multiple aspects of gravitational force calculations. This problem focuses on the interaction between two objects of significantly different masses, similar to calculating the gravitational force of a planet on a smaller object.
The problem involves a 1.0 kg object located 7.0 x 10⁸ m from the center of a larger object with a mass of 2.0 x 10³⁰ kg. Students are asked to solve four related questions:
a) Calculate the force acting on the smaller object. b) Determine the force acting on the larger object. c) Find the acceleration of the smaller object when released. d) Calculate the acceleration of the larger object when released.
Highlight: This problem emphasizes Newton's Third Law of Motion, showing that the gravitational force is equal and opposite for both objects, regardless of their mass difference.
Example: The solution demonstrates that the gravitational force between the objects is 272.245 N, acting on both the smaller and larger objects.
The problem also introduces the concept of acceleration due to gravity by combining the gravitational force formula with Newton's Second Law of Motion . This allows students to calculate the vastly different accelerations experienced by objects of greatly varying masses under the same gravitational force.
Vocabulary: Acceleration due to gravity is the rate at which an object's velocity changes due to gravitational force.
By solving this multi-part problem, students gain a deeper understanding of how gravitational force equations and solutions apply to real-world scenarios, such as the interaction between planets and smaller celestial bodies or objects on their surface. This comprehensive example ties together various concepts related to universal gravitation and provides valuable practice in applying gravitational force formulas to complex situations.

This page introduces a set of practice problems focused on universal gravitation. Students are presented with the fundamental equation for gravitational force: Fg = Gm₁m₂/r². The page also provides additional formulas for solving related problems, such as finding distance or mass when other variables are known.
Definition: Universal gravitation is the force of attraction between all masses in the universe, described by Newton's law of universal gravitation.
Highlight: The gravitational constant G is given as 6.67 x 10⁻¹¹ N*m²/kg², which is crucial for solving these problems.
Two specific problems are presented on this page:
Example: For the first problem, the solution shows that the gravitational force between the two objects is 3.557 x 10⁻⁴ N.
These problems demonstrate how to apply the gravitational force formula to real-world scenarios, helping students understand the concept of calculating gravitational force between objects with mass.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend
