- Equilibrium: This occurs when the net force acting on the object is zero. In this state, the object is either at rest or moving with a constant velocity.
- Free fall: This occurs when the only force acting on the object is gravity. In this state, the object accelerates towards the center of gravity.
- Projectile motion: This occurs when an object is launched with an initial velocity and then only experiences the force of gravity. In this state, the object follows a parabolic path.
