For a body in vertical projectile motion, what shapes do the position, velocity and acceleration graphs against time take?

1. Position depends on time squared for uniform acceleration, so that graph curves as a parabola. 2. Velocity changes by the same amount every second, so that graph is a straight line. 3. The acceleration due to gravity never changes, so that graph is a horizontal constant. 4. Reading them in the order position, velocity, acceleration gives parabola, straight line, constant. 5. Swapping the first two would describe motion at constant velocity instead, which is not projectile motion. _Source: Siyavula Physical Sciences Grade 12 (Everything Science, CC BY 4.0), Chapter 3: Vertical projectile motion in one dimension_
