Gravity

Gravity. Gravity: The force that objects exert on each other because of their masses. Weight: Mass plus the gravity pulling on the object. Strength of gravity depends on :. 1. mass (greater mass = greater gravitational force) 2. distance (greater distance = less gravitational force).

  1. Gravity

  2. Gravity: The force that objects exert on each other because of their masses. • Weight: Mass plus the gravity pulling on the object

  3. Strength of gravity depends on: • 1. mass (greater mass = greater gravitational force) • 2. distance (greater distance = less gravitational force)

  4. Mass of objects • Which person will weigh more? • Why?

  5. Distance • Which object will exert greater gravitational force on the space ship? • Why?

  6. Distance and mass • Which object will exert greater gravitational force? • Why? • Could they ever become equal?

  7. Acceleration • Gravity accelerates all objects at 9.8 m/s2 (on earth) • Terminal velocity- when air resistance equals gravitational force= zero acceleration • Gravity is universal- it’s rules apply everywhere and every time

  8. Description: basketball and tennis ball dropped at the same time • Observations:

  9. Bullets shot vs. bullet dropped • Which will hit first? ?
