The gravitational force exerted on an astronaut on Earth's surface is 650 N down. When she is in the international space station, the gravitational force on her is:
Correct answer: C. Smaller
- A. Larger
- B. Exactly the same
- C. Smaller
- D. Nearly but not exactly zero
Explanation
Please note that the correct option for the gravitational force on the astronaut in the International Space Station (ISS) is c) Smaller. The force is smaller due to the microgravity environment created by the ISS's orbital motion around the Earth.

About Simple Harmonic Motion
Simple harmonic motion is oscillation in which acceleration is directly proportional to displacement and directed toward the equilibrium position. Work includes displacement, velocity, acceleration, phase, period, frequency, amplitude and energy, with applications to springs and simple pendulums. The restoring force and the conditions for SHM distinguish it from general periodic motion.
