A 50 kg object on Earth weighs about how many newtons? (Use g = 9.8 m/s²)
A planet has twice the mass of Earth but the same radius. How does its surface gravity compare to Earth's?
A satellite orbits Earth at a constant speed. What force keeps it moving in a circle?
Describe how gravity affects the tides on Earth.
Describe what would happen to a satellite if Earth's gravity suddenly became much weaker.
Explain why a ball thrown upwards on Earth eventually falls back down.
Explain why astronauts appear to float inside the International Space Station.
Explain why the gravitational force between two asteroids in space is much weaker than the force between the Earth and the Moon.
If an astronaut weighs 60 kg on Earth, what would be their approximate weight on the Moon, where gravity is about 1/6th that of Earth?
If the distance between two objects is doubled, what happens to the gravitational force between them?
If the mass of one object is tripled, how does the gravitational force between it and another object change?
