Why velocity in graph 1 is positive and in graph 2 is negative?
I don't think so. The acceleration is negative in all three plots.sojsail said:Could it be that you intended to ask about acceleration?
A velocity-time graph is a visual representation of an object's velocity over a period of time. It shows how the velocity of an object changes over time, with time on the x-axis and velocity on the y-axis.
A positive velocity-time graph shows that the object is moving in the positive direction with a constant or increasing velocity. The steeper the slope of the graph, the greater the object's velocity.
A negative slope on a velocity-time graph indicates that the object is moving in the negative direction, or slowing down. The steeper the slope, the greater the object's deceleration.
Yes, the velocity-time graph can show an object's acceleration by looking at the slope of the line. A steeper slope indicates a greater acceleration, while a flatter slope indicates a constant velocity.
A velocity-time graph shows the relationship between an object's velocity and time, while a position-time graph shows the relationship between an object's position and time. A velocity-time graph can be used to calculate an object's position, and a position-time graph can be used to calculate an object's velocity.
