Given a velocity time graph how do you determine when the object is moving at the lowest speed is it when V=O or when the gradient is the less steepest? Do the terms "moving at lowest speed" and "moving slowest" mean the same
Anyone have a answer
Just read it straight of the graph. Closest point to v = 0.
Slope of a v/t curve is acceleration...
To determine when the object is moving at the lowest speed in a velocity-time graph, you need to consider both the value of velocity (V) and the gradient of the graph.
1. When V = 0: If the velocity is zero, it indicates that the object is momentarily at rest. In other words, the object is not moving at all. Therefore, when V = 0, the object is not moving and its speed is at its lowest.
2. When the gradient is the least steep: The gradient of a velocity-time graph represents the rate of change of velocity. A less steep gradient in the graph indicates a slower change in velocity. When the gradient is the least steepest (flattest), it means the velocity is changing at a slower rate, indicating that the object is moving at a slower speed. Therefore, when the gradient is the least steep, the object is moving at its lowest speed.
Now, regarding the terms "moving at lowest speed" and "moving slowest," they essentially mean the same thing. Both terms refer to the object's speed being at its minimum or the slowest value. So, when you are asked to determine when the object is moving at the lowest speed in a velocity-time graph, you can look for either the point where V = 0 or where the gradient is the least steep.
