v_{f} = v_{i} + a t

x_{f} = x_{i} + ½ ( v_{i} + v_{f} ) t

x_{f} = x_{i} + v_{i} t + ½ a t^{2}

v_{f}^{2} = v_{i}^{2} + 2 a ( x_{f} - x_{i} )

Freefall | A freely falling object moves freely under the influence of gravity alone. When air resistance is ignored (a vaccuum is a simplification model) then the object is in free fall. Magnitude of free-fall acceleration is denoted by |

Uniform Circular Motion | In uniform circular motion, a particle moves in a circle at constant speed. However, the acceleration is constantly changing. This is because acceleration is a change in velocity, the velocity vector is changing direction. The acceleration vector is always perpindicular to the path and always points toward the center of te circle. This is centripetal acceleration, and its magnitude is defined by the equation below. a |
