AND B STUDY GUIDE 2026 QUESTIONS WITH
SOLUTIONS GRADED A+

◉ Velocity (v). Answer: -Speed and direction
-Measured in meters per second (m/s)
average v = Δx/t


◉ Acceleration (a). 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. 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. Answer: -Slope represents average
velocity
-Object changes direction when graph crosses x-axis

, ◉ Velocity vs. Time Graph. Answer: -Slope represents average
acceleration
-Area represents displacement


◉ Acceleration vs. Time Graph. Answer: -Area represents change in
velocity


◉ Scalars. Answer: Quantities with only a size/magnitude (ex:
speed, mass, length, temperature, time, distance, energy, etc.)


◉ Vectors. Answer: Quantities with both a size and direction (ex:
displacement, velocity, position, acceleration, force, etc.)


◉ Projectile Motion. Answer: -Horizontal and vertical components
are independent of each other
-Complementary angles travel same horizontal distance
-Larger angles travel higher and spend more time in air, while
smaller angles have greater horizontal velocities


◉ Force (F). Answer: -A push or pull
-Measured in Newtons (N)
