Objects moving at high speeds relative to an observer experience time more slowly.

Examiners look for specific "trigger words." For example, when defining a projectile , don't just say "an object thrown." Define it as an object upon which the only force acting is gravity (neglecting air resistance).

If you are currently studying for your exams, here are three essential strategies to move from a Grade B to an A*:

In Advanced Physics, we break time dilation into two distinct effects: Objects moving at high speeds relative to an

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

Time passes more slowly in stronger gravitational fields. Always include units in every final value

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
