Example questions: Define potential and kinetic energy. Calculate the average speed from a given distance and time. Differentiate between renewable and non-renewable energy sources.

[{"question":"Define and differentiate between potential and kinetic energy.","answer":"Potential energy is the stored energy in an object due to its position or arrangement, while kinetic energy is the energy of motion. A raised weight or a stretched spring is potential energy, whereas a moving car demonstrates kinetic energy."},{"question":"Calculate the average speed of a car that travels 150 km in 3 hours.","answer":"The average speed of the car is calculated by dividing the total distance by the total time. In this case, 150 km divided by 3 hours equals 50 km/h."},{"question":"Explain the difference between renewable and non-renewable energy resources with examples.","answer":"Renewable energy resources are those that can be replenished naturally and are usually sustainable, such as solar, wind, and hydroelectric energy. Non-renewable energy resources, such as coal, oil, and natural gas, take millions of years to form and theirs reserves are being depleted."},{"question":"Draw and interpret a distance-time graph for a trip where a student walks to school at 4 km/h for 30 minutes, stops for a 10-minute break, and then walks another 2 km at the same speed.","answer":"From the graph, you should see a straight line with a slope representing 4 km/h for the initial 30 minutes, a flat line during the 10-minute break, and another rising line at the same slope for the last 2 km."},{"question":"What are the factors affecting the drag force on a high-speed train?","answer":"The factors include the speed of the train, the shape of the train, and the direction of any wind that may be present."}]
