Worked Solution & Example Answer:Figure 3 shows a spinning flywheel - Edexcel - GCSE Physics Combined Science - Question 3 - 2018 - Paper 1
Step 1
State how energy is stored in a spinning flywheel.
Answer
Energy is stored in a spinning flywheel as kinetic energy. This energy arises from the mass of the flywheel and the speed at which it rotates. As the flywheel spins, it maintains a constant rotational motion, which allows it to store energy that can be later released as mechanical work.
Step 2
State one way to increase the amount of energy stored in the flywheel.
Answer
One way to increase the amount of energy stored in the flywheel is to increase the speed of spinning. By applying more torque, the angular velocity of the flywheel can be enhanced, resulting in a higher kinetic energy storage. Additionally, increasing the mass of the flywheel can also contribute to greater energy storage.
