  • What is the acceleration due to gravity on the surface of the Earth?
    The acceleration due to gravity on the surface of the Earth is 9.8 m/s².
  • What is the acceleration of an object falling on Earth?
    The acceleration of an object falling on Earth is 9.8 m/s², assuming air resistance is negligible.
  • Why does the unit 'second' appear twice in the unit m/s² for acceleration due to gravity?
    The unit 'second' appears twice in m/s² because acceleration is the change in velocity (m/s) per unit time (s), so it is meters per second per second.
  • Why does the unit 'second' appear twice in the unit m/s² for free-fall acceleration?
    The unit 'second' appears twice in m/s² because acceleration measures how much the velocity (in m/s) changes each second.
  • How do you determine the mass of a person on the Moon if you know their mass on Earth?
    A person's mass remains the same on the Moon as on Earth; mass does not change with location.
