A velocity-time graph is a visual representation of an object's velocity over time. The horizontal axis represents time, while the vertical axis represents velocity. The slope of the graph at any given point represents the object's acceleration.
To find acceleration on a velocity-time graph, you can calculate the slope of the graph at a specific point. This can be done by dividing the change in velocity by the change in time, or by using the formula a = (vf - vi) / t, where vf is the final velocity, vi is the initial velocity, and t is the time interval.
The unit of acceleration on a velocity-time graph is meters per second squared (m/s^2). This represents the change in velocity over a specific time interval.
To calculate acceleration in the first 15 minutes on a velocity-time graph, you can first determine the initial and final velocities at the 15-minute mark. Then, you can use the formula a = (vf - vi) / t, where t is the time interval of 15 minutes, to find the acceleration in km/h^2.
Yes, acceleration can be negative on a velocity-time graph. This indicates that the object is slowing down or decelerating. A positive acceleration indicates that the object is speeding up or accelerating.
