Terminal Velocity {Ans: The velocity of an object when the force due to air resistance equals the force due to gravity on the object}% Difference {Ans: | Value 1 - Value 2 | / (Value 1 + Value 2 / 2) X 100%}How to solve Average Velocity on a d-t graph? {Ans: Identify the time interval you are analyzing. On the graph,mark points at the beginning time and ending time for the interval you are analyzing. Join the two points by drawing a line between them. Calculate the slope of the line}Run {Ans: Horizontal change between two points on a line}Slope (m) {Ans: A measure of the steepness of a line}Scalar {Ans: A quantity that has only magnitude}Average Speed {Ans: The total distance travelled divided by the total time taken to travel that distance}Instantaneous Velocity {Ans: The velocity of an object at a specific instant in time}How to solve for Instantaneous Velocity? {Ans: Identify the exact time you are analyzing. Marks the instant then using a ruler,estimate a tangent line that touches the instant in Step 2 and sketch the tangent line.}Vector {Ans: A quantity that has magnitude and direction}Position
