Force

The force may be thought of as an influence which tends to change the motion of an object. Forces are inherently vector quantities, requiring vector addition to combine them. The SI unit for force is the …

Acceleration

To accelerate means to speed up. The greater the acceleration, the greater the change in velocity over a given time. The average acceleration is the rate at which velocity changes: \[a_{avg}=\dfrac{\Delta v}{\Delta t}=\dfrac{v_f-v_0}{t_f-t_0}\] …
