Weight, mass and gravitational field strengthIB MYP Physics: Mind map

Exam questions on Weight, mass and gravitational field strength

1. An astronaut of mass 60 kg is training for a mission to the Moon. The gravitational field strength is 10 N/kg on Earth and 1.6 N/kg on the Moon.
   Explain why the astronaut's mass is the same on the Moon, but her weight is different.2 marks
2. A space probe carries a standard mass of 2.0 kg on a newton meter to measure the gravitational field strength at different places. On Earth the newton meter reads 20 N. Near Jupiter it reads 50 N.
   Describe how a newton meter is used to find the weight of the standard mass.2 marks
3. A group of students investigates the relationship between mass and weight on Earth. They hang masses of 0.1, 0.2, 0.3, 0.4 and 0.5 kg from a newton meter. The readings are 1.0, 2.0, 3.1, 4.0 and 5.0 N.
   Describe the trend in the results and calculate the value of weight ÷ mass for the 0.4 kg mass.3 marks
