A body of mass kg was weighed, using a spring scale, at the north pole and at the equator. Assuming m/s2 at the north pole and m/s2 at the equator, what was the difference in the two readings?
The force exerted by the Moon’s gravity is six times smaller than the force that exerted by the Earth’s gravity. The weight of an astronaut plus his space suit on the Moon is 250 N.
How much does the suited astronaut weigh on Earth?
What is the mass of the suited astronaut on the Moon?
What is the mass of the suited astronaut on Earth?
Astronauts in orbit are apparently weightless. This means that a clever method of measuring the mass of astronauts is needed to monitor their mass gains or losses, and adjust their diet. One way to do this is to exert a known force on an astronaut and measure the acceleration produced. Suppose a net external force of 50.0 N is exerted, and an astronaut’s acceleration is measured to be 0.893 m/s2. Calculate her mass.
The mass of a particle is 15.0 kg.
What is its weight on Earth?
On the Moon, the acceleration produced by gravity is 1.63 m/s2. What is its weight of the particle on the Moon?
What is its mass on the Moon?
What is its weight in outer space far from any celestial body?
What is its mass at this point?
