If you are currently studying for your exams, here are three essential strategies to move from a Grade B to an A*:
Have you ever wondered why your phone's GPS is so accurate? It isn’t just clever satellite engineering; it’s a daily proof of . Without correcting for time dilation, your GPS would be off by kilometers within a single day. The Two Faces of Time Dilation
Objects moving at high speeds relative to an observer experience time more slowly.
In Advanced Physics, we break time dilation into two distinct effects:
Even if your final answer is wrong, you can earn the majority of marks for your method and derivations . Always include units in every final value. Why Physics Matters
For a GPS satellite, these two effects are in a constant "tug-of-war." The satellite's high orbital speed slows its clock down by about 7 microseconds per day. However, because it is much further from Earth's mass, gravity is weaker, causing its clock to run faster by about 45 microseconds per day. The net result? The satellite clock gains 38 microseconds every day compared to us on the ground. 💡 Top Tips for A-Level Physics Success
Time passes more slowly in stronger gravitational fields.
