What does a distance-time graph show?
A distance-time graph shows how the distance of an object from a point changes over time.
What does a horizontal line on a distance-time graph represent?
A horizontal line on a distance-time graph represents an object that is not moving (it is stationary).
True or False?
If a distance-time graph has a positive gradient then the object is moving further away from the original point.
True.
If a distance-time graph has a positive gradient then the object is moving further away from the original point.
What does the gradient of a distance-time graph represent?
The gradient of a distance-time graph represents the speed at which the object is moving.
True or False?
If a distance-time graph has a straight line then the speed of the object is increasing.
False.
If a distance-time graph has a straight line then the speed of the object is constant.
What does a speed-time graph show?
A speed-time graph shows how the speed of an object changes over time.
What does a horizontal line on a speed-time graph represent?
A horizontal line on a speed-time graph represents an object moving with a constant speed.
What does the gradient of a speed-time graph represent?
The gradient of a speed-time graph represents the acceleration of the object.
What does the area underneath a speed-time graph represent?
The area underneath a speed-time graph represents the distance that the object has travelled.
True or False?
If a speed-time graph has a negative gradient then the object is slowing down.
True.
If a speed-time graph has a negative gradient then the object is slowing down.
True or False?
When a speed-time graph touches the horizontal axis, it means that the object is back where it started.
False.
When a speed-time graph touches the horizontal axis, it means that the object is not moving (it is at rest).
