An exploration probe is deployed on the surface of a distant planet.
The mass of the probe is 420 kg. The acceleration of free fall on the surface of this planet is 4.5 m/s2.
State what is meant by the term weight.
Calculate the weight of the probe on the planet.
The probe releases a balloon from a point that is a small distance above the surface of the planet. The atmosphere at the surface of this planet has a density of 0.60 kg/m3. The inflated balloon has a mass of 150 g and a volume of 0.20 m3.
Make an appropriate calculation and then predict and explain the direction of any motion of the balloon. Show your working.
