if I was given a graph, and told to work out the instant and average velocity, do I just find the slope of a tangent for both instant and average velocity? thx~
Instant velocity refers to the velocity at a specific moment in time, while average velocity refers to the overall velocity over a certain period of time.
Instant velocity is calculated by finding the derivative of an object's position with respect to time. It is the slope of the position-time graph at a specific point.
Yes, instant velocity can be negative. This means that the object is moving in the opposite direction of the positive direction on the position-time graph.
A negative average velocity indicates that the object has moved in the negative direction over the specified time period, or that it has moved backwards.
Acceleration affects instant velocity by changing the speed and/or direction of an object at a specific point in time. Average velocity takes into account the changes in velocity over a certain period of time, so acceleration can also affect average velocity.
