Is there gravity in space? Explain why? If an astronaut leaves his air-filled space station and
takes his guitar out into space on a spacewalk, another astronaut will not be able to hear the
sound guitar as he plays it. Why? Moon's radius distance from the centre of the Earth is given
by ‘R’. If this radius is increased to 1.5 times ‘R’, how would this change affect the magnitude
of gravitational force of the Earth on the Moon? How would you compare the gravitational force
on a 1 kg on the surface of moon with respect to the force for the same mass on Earth?
(Given: Mass of Earth (Me)=5.97 x1024 kg, mass of Moon (Mm) = 7.4X1022 kg, radius of
earth =6400 km and radius of Moon = 1730 km)

A space station is located in a gravity-free region of space. It consists of a large diameter, hollow thin-walled cylinder which is rotating freely about its axis. It is spinning at a speed such that the apparent gravity on the inner surface is the same as that on earth. The cylinder is of radius r and mass M. (a) What is the minimum total work which had to be done to get the cylinder spinning up to speed. (b) Radial...

An astronaut is floating inside the international space station at rest--and since there are no other external forces she can rely on to change her state of motion--she decides to throw her jacket across the room. If her mass is 66.9kg and she throws the 1.1kg jacket at 14.7 m/s -- what is her recoil speed?

A space station has a large ring-like component that rotates to simulate gravity for the crew. This ring has a mass M = 2.1×10^5 kg and a radius of R= 86.0 m and can be modeled as a thin hoop. Before spinning up the ring section, crew members Dave and Frank dock their ships, each with mass m= 3.5×10^4 kg on two docking ports located on opposite sides of the center of the ring. The docking ports are located r...
