Question

True or false. The equation vf=vi accurately describes the motion of an object that experiences constant non-zero acceleration

Answer 1

False. The equation \( v_f = v_i \) represents a scenario where there is no change in velocity, meaning the acceleration is zero. For an object experiencing constant non-zero acceleration, the correct equation that relates initial velocity (\( v_i \)), final velocity (\( v_f \)), acceleration (\( a \)), and time (\( t \)) is \( v_f = v_i + a t \).
