Reading Comprehension — Gravity Read the passage, then answer the questions below. Newton's law of universal gravitation describes gravity as a force proportional to mass and inve rsely proportional to the square of the distance between objects. It explains planetary orbits, tides, and why you weigh less on the Moon (1/6 o f Earth's pull). But Newton couldn't explain how gravity works across empty space. Einstein's ge neral relativity reframed it: massive objects cu rve spacetime itself, and other objects follow t hose curves. This was confirmed in 1919 when sta rlight bent around the Sun during an eclipse—exa ctly as Einstein predicted. Today, GPS satellite s must account for relativistic time dilation ca used by Earth's gravity, or your phone's locatio n would drift by kilometers daily. Questions: 1 How does Einstein's view of gravity differ from Newton's? 2 What evidence confirmed Einstein's theory in 1919? 3 Why do GPS satellites need to account for gravity's effect on time? www.littleactivity.com 8th Grade — Page 1
