Question

what is determined by calculating the slope of the position vs time graph?
position
velocity
distance
displacement

Explanation:

In a position - vs - time graph, the slope is calculated as the change in position (Δx) divided by the change in time (Δt), which is the formula for velocity ($v=\frac{\Delta x}{\Delta t}$). Position is the y - axis value, distance is a scalar related to path length, and displacement is a vector change in position, but the slope of position - time graph gives velocity.

Answer:

B. velocity
