Can you use the material I already have?

Drag across.

Sample

Orbits

  1. Throw a ball sideways and it falls to the ground.
  2. Throw it faster and it lands further away.
  3. The Earth curves away beneath it.
  4. At about 8 km/s the ground curves away as fast as the ball falls.
  5. It keeps falling but never lands. That is an orbit.
  6. Gravity gives the centripetal force: v = √(GM/r).

Fire it faster. Where does it land?

Will it mark the way I mark?

Switch a rule.

Sample

A stone is dropped from 20 m. How long does it take to land? Take g = 10 m/s². [4]

  1. s = ½gt²
  2. 20 = ½ × 10 × t²
  3. t² = 20 × 5 = 100
  4. t = 10
