FAQs on Distance time graphs Video Lecture - Year 8 Physics (Cambridge)

1. How can distance-time graphs be used to calculate speed?
Ans. Distance-time graphs can be used to calculate speed by finding the gradient of the graph, which represents the speed. The steeper the gradient, the faster the speed.
2. What does a horizontal line on a distance-time graph indicate?
Ans. A horizontal line on a distance-time graph indicates that there is no change in distance over time, meaning the object is stationary or not moving.
3. How can you determine the distance traveled by an object from a distance-time graph?
Ans. The distance traveled by an object can be determined by calculating the area under the distance-time graph. This can be done by finding the area of the shape formed by the graph.
4. What does a curved line on a distance-time graph signify?
Ans. A curved line on a distance-time graph signifies that the speed of the object is changing. The steeper the curve, the greater the acceleration or deceleration.
5. How do you interpret a negative slope on a distance-time graph?
Ans. A negative slope on a distance-time graph indicates that the object is moving in the opposite direction. The steeper the negative slope, the faster the object is moving in the opposite direction.
