A 10 kg bag of rice is taken to the Moon, where g = 1.62 N/kg. What does it weigh there, in newtons?

A 25 kg sample container is taken to Mars, where g = 3.72 N/kg. What does it weigh there, in newtons?

An astronaut with all her equipment has a mass of 65 kg. What is her weight on Earth, in newtons? (g = 9.8 N/kg)

A 65 kg astronaut steps onto an Earth-calibrated spring bathroom scale while visiting a lunar base (g = 1.62 N/kg). What number, in kilograms, would the scale display? Give your answer to two decimal places.

A suitcase weighs 297.5 N on Jupiter’s cloud tops, where g = 24.79 N/kg. What is its mass, in kilograms?

A rock weighs 93.0 N on Mars (g = 3.72 N/kg). What would the same rock weigh on the Moon (g = 1.62 N/kg)? Work out its mass first.

Ignoring air resistance, how far does an object fall from rest in 1 second on Earth? (g = 9.8 m/s²)

Ignoring air resistance, how far does an object fall from rest in 4 seconds on Earth?

Ignoring air resistance, what is the speed of an object after falling for 5 seconds? Give your answer in m/s.

A stone is dropped and takes 4.04 seconds to hit the ground. Roughly how high, in metres, was it dropped from? (No air resistance; round to the nearest metre.)

A ball is dropped from a height of 80 m. Ignoring air resistance, how fast is it moving when it lands? Give your answer in m/s.
