31.The strength of gravity at the Earth's surface is 10 Newtons per
kilogram. Calculate the weight of a car with a mass of 1500 kg.
32.The strength of gravity on the Moon is 1.6 Newtons per kilogram.
If an astronaut's mass is 80 kg on Earth, what would the
astronaut’s weight be on the Moon?
33. Astronauts say they feel weightless when they’re in space. Explain
why?
