Question 1
What formula expresses Newton's law of universal gravitation?
- F = G * (m1 * m2) / r²
- F = m * a
- F = G * (m * r²)
💡 Hint: Think about the relationship between mass and distance in gravity.
Question 2
True or False: Gravitational potential energy is always positive.
- True
- False
💡 Hint: Remember what happens as mass moves far away from the gravitational source.

Challenge Problems
Push your limits with challenges.
Question 1
Two masses, 5 kg and 10 kg, are 3 m apart. Calculate the gravitational force between them.
💡 Hint: Be careful with the units as they all need to be consistent.
Question 2
If another mass of 2 kg is added between the two masses from the previous problem, affecting the total gravitational force, calculate the new force.
💡 Hint: Use the force calculations you did previously and consider the distances carefully.
