### constant velocity, no acceleration (0)

a straight line graph

displacement

### slope

how to determine the y-intercept of a velocity time graph

### the object is not moving

if the slope of a distance time graph is 0, then the...

### velocity is 0, acceleration is 0

if the object is not moving

### constant negative velocity no acceleration, negative velocity time graph intercept

if the line in a distance time graph is a straight line downward

### velocity constantly increase

if the distance time graph is an upward parabola

### (1/2)vt

how to calculate the displacement of a graph of velocity time graph that is constantly increasing

### dots continue spacing farther

a motion particle model is like this when a distance time graph is a parabola

### dots continue at an equal distance apart going forward

a motion paritcle model is like this when a distance time graph is linear and going upward

### dots continue at an equal distance apart going backward

a motion particle model is like this when a distance time graph is linear and going downward

### a*t

change in velocity on an acceleration time graph equals
