Motion[edit]   Linear Motion with constant speed over time[edit]
• Speed v(t) = V   • Acceleration a(t) = 0   • Distance s(t) = V
t  Linear Motion with changing speed over time[edit]  For any
Linear Motion travels at different speed at different time  v1
at t1 v at t   • Change in Speed \Delta v =  v - v_o   • Change
in Time ∆t = t - t_o     • Rate of Change of Speed over Time   a
= \frac{\Delta v}{\Delta t} = \frac{v - v_o}{t - t_o}  \Delta v
