1) What is the location where your weight would be the greatest using this picture of the solar system? a) Mercury b) Venus c) Mars d) Jupiter e) Saturn f) Neptune 2) What planet would you have the same weight as Earth? a) Mercury b) Saturn c) Mars d) Uranus e) Moon f) Neptune 3) What is the formula to calculate weight? a) weight (N) = mass (kg) / 10 (N/kg) b) weight (kg) = mass (N) x 10 (N/kg) c) weight (N) = mass (kg) x 10 (N/kg) d) mass (kg) = weight (N) / 10 (N/kg) e) 10 (N/kg) = weight (N) / mass (kg) 4) Calculate the weight of a 25kg mass on Mars. Do not just guess, actually calculate it!! a) 6.76 kg b) 0.148 kg c) 92.5 kg d) 6.76N e) 0.148N f) 92.5N 5) How would your mass on Earth compare with your mass on Mercury a) Mass would be more on Mercury because the gravity is less than Earth b) Mass is less on Mercury because gravity is less than Earth c) Mass would be the same d) You cannot compare masses on different planets, only weight! e) 92.5N 6) The strength of gravity on Earth is 10 N/kg. What is the weight of an adult who has a mass of 75 kg? a) 75 N b) 750 N c) 150 N d) 7.5 N e) 7.5 kg f) 375 N 7) The strength of gravity on Earth is 10 N/kg. What is the mass of a car that has a weight of 8500 N? a) 85 kg b) 850 kg c) 8500 kg d) 850 N e) 8.5 N f) 85000 N 8) When you stand on a scale, and it displays your mass in kilograms (kg), what is it actually measuring? a) The force of gravity b) Your height c) Your density d) The scale's accuracy e) Your weight f) Your mass, that's why it says kg! 9) Why does a spacecraft require a larger force to travel from Earth to the Moon compared to coming back from the Moon to Earth? a) Because the Moon has a stronger gravitational force. b) Because the spacecraft gains weight on its journey to the Moon. c) Because the Earth has a stronger gravitational force. d) Because the Moon's surface is rough and slows down the spacecraft. e) Because the spacecraft has more fuel when leaving the Moon.
