AP Physics 1 Exam questions with correct answers

Displacement (Δx) CORRECT ANSWER -Net change in position -Measured in meters (m) Δx = x(f) - x(i) Velocity (v) CORRECT ANSWER -Speed and direction -Measured in meters per second (m/s) average v = Δx/t Acceleration (a) CORRECT ANSWER -Rate of change of velocity w/ respect to time -Measured in meters per second squared (m/s^2) average a = Δv/t Speeding up vs. Slowing Down CORRECT ANSWER -Speeding up occurs when velocity and acceleration have the same sign -Slowing down occurs when velocity and acceleration have opposite signs Position vs. Time Graph CORRECT ANSWER -Slope represents average velocity -Object changes direction when graph crosses x-axis Velocity vs. Time Graph CORRECT ANSWER -Slope represents average acceleration -Area represents displacement
