Quick questions on Kinetic and gravitational potential energy - CCEA GCSE Physics
5short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What is kinetic energy?Show answer
This is why braking distance rises sharply with speed: a faster car has much more kinetic energy to remove.
What is gravitational potential energy?Show answer
Lifting an object transfers energy from your chemical store (via work done) to its gravitational potential store.
What is q1?Show answer
Calculate the kinetic energy of a ball moving at . [2 marks]
What is q2?Show answer
Find the gravitational potential energy gained when a mass is raised , . [2 marks]
What is q3?Show answer
Why does doubling a car's speed have such a big effect on its kinetic energy? [2 marks]
