GCSE Physics Revision "Distance-Time Graphs"
Freesciencelessons・2 minutes read
Constructing a distance-time graph is key to determining an object's speed, with tangents used by higher-tier students to find the speed of accelerating objects. The gradient of the graph reveals the object's speed, with upward slopes indicating acceleration and tangents used to calculate speed at specific points.

Constructing Distance-Time Graphs for Speed Analysis
- Ability to construct a distance-time graph from given information is crucial for determining an object's speed, with higher-tier students able to use tangents to find the speed of an accelerating object.
- Representing a journey on a distance-time graph involves plotting points for distance and time, connecting them with straight lines, and calculating speed by dividing distance by time for each segment.
- The gradient of a distance-time graph indicates the object's speed, with upward sloping curves showing acceleration, and the ability to determine speed at specific points by drawing tangents and calculating gradients.
