when the velocity of an object speeds up and then slows down, how its gragh will look like
When the velocity of an object speeds up and then slows down, the graph of its velocity vs. time will appear as a V-shaped curve. Initially, the slope of the graph will be positive, indicating an increasing velocity. As time progresses, the slope will decrease and eventually become negative, implying a decrease in velocity. The turning point on the graph, where the slope changes from positive to negative, represents the moment when the object starts to slow down.
When the velocity of an object speeds up and then slows down, the corresponding graph of velocity versus time will generally appear as follows:
1. Initially, the graph will show a positive slope indicating an increase in velocity. This indicates that the object is speeding up.
2. At a certain point, the graph will reach a peak or maximum value. This represents the point where the object has achieved its highest velocity.
3. After the peak, the graph will start to show a negative slope, indicating a decrease in velocity. This means that the object is slowing down.
4. Finally, the graph will level off and reach zero velocity. This implies that the object has come to a complete stop.
In summary, the graph of velocity versus time will start with a positive slope, reach a peak, then show a negative slope, and eventually level off to zero.
