Gravity Pulls Things Down

重力使物体下落

Description

Understand gravity as a force that pulls objects towards the centre of the Earth, that 'down' means towards Earth’s centre regardless of where you stand on the sphere, and that gravity keeps the Moon orbiting Earth and planets orbiting the Sun

Mastery Evidence
  • Define gravity as a pulling force that attracts objects towards the centre of the Earth
  • Explain that 'down' points towards Earth's centre, so people on opposite sides of the globe both feel pulled 'down'
  • State that gravity keeps the Moon orbiting Earth and planets orbiting the Sun
Assessment Prompt

Can your child explain why things fall 'down' and that gravity is the same force keeping the Moon going around the Earth?
