General Science Essentials
Work in physics equals force times distance . When you push or pull something over a distance, you're doing work! This concept shows up frequently on tests.
Energy comes in different forms. Kinetic energy is the energy of motion, while potential energy increases with height. This explains why dropping objects from higher up creates bigger impacts.
💡 The water displacement method helps find an object's volume: just measure how much water it displaces. If water level rises from 17.8 mL to 23.6 mL when an object is submerged, the object's volume is 5.8 mL.
Weather patterns result from temperature differences. Convection occurs when air moves from hot places to cold places, creating phenomena like sea breezes and land breezes. This movement happens because sea and land heat up and cool down at different rates.
Earth's structure includes several key features. The crust forms Earth's hard outer shell, while mountains form when tectonic plates collide. Volcanoes like Mount Mayon are classified as composite volcanoes because they form from alternating quiet and violent eruptions.
