Physics Quiz: Projectile Motion

The vertical acceleration is equal to gravitational field strength (g).

Terminal velocity is the maximum velocity reached when the forces acting on a falling object become balanced, resulting in zero acceleration.

Friction is a resistance to motion between an object and a surface or an object moving through a fluid, and it acts in the opposite direction to the movement.
