Understanding Distance-Time Graphs in GCSE Physics

Learn to interpret distance-time graphs and calculate speed using gradients. Straight lines indicate constant speeds, flat lines mean stationary, and curved lines represent changing speeds.

00:00:04 This video explains distance-time graphs and how to interpret them. It emphasizes that the gradient of the graph represents the speed of the object.

πŸ“ Distance-time graphs show how far something has traveled in a certain period of time.

πŸ“ˆ The gradient of the line on a distance-time graph represents the speed of the object.

πŸš΄β€β™€οΈ In the example given, the cyclist traveled a total of 50 meters in 11 seconds.

00:01:09 This video explains distance-time graphs in GCSE Physics, including how to interpret gradients and identify periods of constant speed, stationary, acceleration, and deceleration.

πŸ“ The gradient on a distance-time graph represents speed.

πŸšΆβ€β™€οΈ A flat line indicates stationary position with zero speed.

πŸ“ˆ A steeper line indicates increasing speed and acceleration.

00:02:13 This video explains how to find speed on a distance-time graph using tangents. Straight lines indicate constant speeds, flat lines mean stationary, and curved lines represent changing speeds.

πŸ“ Straight lines on a distance-time graph indicate constant speeds.

⏸️ Flat lines on a distance-time graph represent stationary objects.

πŸ”„ Curved lines on a distance-time graph indicate changing speeds.

00:03:16 Learn how to calculate the gradient of a distance-time graph by dividing the change in distance by the change in time, both for straight lines and curves.

πŸ“ˆ Calculate the gradient of a straight line by dividing the change in distance by the change in time.

πŸ” When the point lies on a curve, draw a tangent to the curve at that point and calculate the gradient of the tangent.
