Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the gravitational force between two masses m₁ and m₂ separated by distance r?
- F = G (m₁ m₂) / r
- F = G (m₁ m₂) / r^2
- F = (m₁ m₂) / (G r^2)
- F = G m₁ + m₂
💡 Hint: Focus on how distance is defined in the formula.
Question 2
True or false: Gravitational potential energy increases as two masses are moved apart.
- True
- False
💡 Hint: Think about how energy changes with distance.

Question 1
A satellite of mass 1000 kg orbits Earth (mass = 5.97 x 10^24 kg) at a height where the gravitational field strength is 5 N/kg. Find the orbital radius and speed.
💡 Hint: Make sure to add the radius of Earth to the height.
Question 2
Two objects are 10m apart, mass A is 5 kg, and mass B is 10 kg. Calculate the gravitational force between them using G = 6.674 x 10^-11 N(m/kg)².
💡 Hint: Don’t forget to square the distance.
