## Create a new folder

a = ∆v/t

### Acceleration is zero

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

∆v = vf - vi

slope = velocity

### Graph: velocity (speed) vs. time (slope)

slope = acceleration

### Negative accelerations

speed is decreasing

### Negative velocity

object moving backwards

A straight line

A straight line

### Positive accelerations

speed is increasing

### Positive velocity

object moving forward

### SI unit for acceleration

m/s² (meters per second squared)

meter

### SI unit for speed/velocity

m/s (meters per second)

seconds

### Speeding up, slowing down, turning

examples of acceleration (3)

### Velocity

speed and direction

v = d/t

### Velocity is zero

object is not moving
