Vector | Magnitude with direction |
Scalar | Magnitude without direction |
Velocity | speed with direction |
Translational motion | any change in motion |
Rectilinear motion | motion in a straight line |
Curvilinear motion | motion in a curved line |
Displacement | straight line distance between 2 points |
Sign convention | way of showing positive and negative direction dependent on a point of reference |
Point of reference | point that all motion is compared to |
Deceleration | slowing to a stop, regardless of the initial direction |
Formula for velocity | v= d/t |
Formula for acceleration | a=vf-vi/t |
Free fall | object being pulled towards the earth with gravity being the only force acting on it (ignoring air resistance) |
Terminal velocity | Fastest velocity an object can fall |
Formula for displacement | d= vi x t + 1/2 a x t^2 |
