d-t Graph • Straight line = constant velocity (uniform motion) • Curved line = changing velocity (non-uniform motion) • Slope of line = velocity
v-t Graph • Horizontal line = no acceleration • Straight, non-horizontal line = constant acceleration (uniformly accelerated motion) • Curved line = changing acceleration (non-uniformly accelerated motion) • Slope of line = acceleration • Area under curve = displacement
a-t Graph • Horizontal line = constant acceleration (uniformly accelerate motion) • Non-horizontal line = changing acceleration (non-uniformly accelerated motion) • Area under curve = change invelocity
