Physics: Year 9 Term 1: GPE 1.0 / 5 based on 1 rating ? PhysicsEnergyGCSEAQA Created by: Charlotte HerondaleCreated on: 21-10-17 12:33 What is GPE? (1) The energy gained via height 1 of 7 Why does GPE increase when an object is lifted? (1) Work is done to overcome gravity 2 of 7 What is the approximate strength of gravity on Earth? (1) 10 3 of 7 What is the equation for GPE? (1) Change in GPE (J) = weight (N) x change in height (m) 4 of 7 What is the meaning of Δ (delta) in physics equations? (1) Change in 5 of 7 The gravity on the moon is what fraction of that on earth? (1) 1/6 (if E=10, M~1.7) 6 of 7 What is the equation for GPE a different strength of gravity? (1) Change in GPE (J) = mass (kg) x gravity strength (N/kg) x change in height (m) 7 of 7
