Conceptual Questions on Projectile Motion in Physics

True or false questions testing conceptual understanding of projectile motion equations with answers.

Questions with Answers

A projectile is launched (air resistance negligible). Which statements are true?

Any object with gravity as the only force is a projectile.
Projectile motion involves constant horizontal velocity and constant vertical acceleration \(a = g\).
The vertical component of velocity \(v_y\) is constant.
The horizontal component of velocity \(v_x\) is constant.
The acceleration \(\vec{a}\) is constant.
The kinetic energy \(K = \frac{1}{2}mv^2\) is constant.
The potential energy \(U = mgh\) is constant.
The total mechanical energy \(E = K + U\) is constant.
The minimum speed equals the horizontal velocity component \(v_x\).
The horizontal velocity \(v_x\) varies linearly with time \(t\).
The horizontal displacement \(x(t)\) varies linearly with time \(t\).
The vertical displacement \(y(t)\) varies linearly with time \(t\).
The trajectory is parabolic: \(y(x) \propto x^2\).
