### SI unit for speed/velocity

m/s (meters per second)

### SI unit for acceleration

m/s² (meters per second squared)

### Positive accelerations

speed is increasing

### Negative accelerations

speed is decreasing

### Acceleration is zero

the object is not chaning speed (is not moving or is moving with constant speed)

### Positive velocity

object moving forward

### Negative velocity

object moving backwards

### Velocity is zero

object is not moving

### Velocity

speed and direction

slope = velocity

A straight line

### (distance vs. time) constant speed forward

straight line, positive slope

### (distance vs. time) standing still

straight line, slope = 0 (line is flat)

### (distance vs. time) speeding up (accelerating)

smiling curve (slope gets steeper and steeper)

### (distance vs. time) slowing down

frowning curve (slope gets flatter and flatter)
