Projectile motion = motion of an object moving freely under gravity (neglecting air resistance) after it is launched.
Correct choices: a, c, e.
- a) Kicking/punting a football — yes: after the kick it flies freely under gravity (a projectile).
- c) A free throw in basketball — yes: after release the ball follows a ballistic arc.
- e) A person throwing darts — yes: after release the dart travels under gravity.
Not projectile motion:
- a car on a highway — no: it’s constrained by the road and propelled by the engine/tires.
- a ball rolling downhill — no: it stays in contact with the surface, so normal and friction forces act.
