A 10 kg object is taken to the Moon, where gravity is 1.6 m/s². What is its weight on the Moon?
A 5 kg object is on a planet where g = 15 m/s². What is its weight?
A 60 kg astronaut weighs 588 N on Earth. What is the value of g on Earth used in this calculation?
A student drops a ball from a height of 5 meters on Earth. Ignoring air resistance, what is the speed of the ball just before it hits the ground? (Use g = 9.8 m/s²)
