First thing first: We're discussing Motion in Physics, and more precisely, the three (well, actually four, but we don't use the last one that often) equations of motion. These equations are your toolkit when dealing with questions about, well, motion!
Imagine you're in a car (🚗 vroom vroom) that's accelerating. You start with some initial speed u
, then you put the pedal to the metal, and after some time t
, you're at a new speed v
. This is described as v = u + at
. It's like saying "my new speed is my old speed plus all that acceleration over time".
in that car. It's like calculating the area under the graph of speed vs time (remember, area under graph = sum of all tiny pieces of distance travelled at each moment). The equation s= ut + ½at²
tells us just that. It says "the total distance covered is initial speed times time plus half the product of acceleration and square of time".
