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
Speeding up, slowing down, turning
examples of acceleration (3)
velocity formula
v = d/t
acceleration formula
a = ∆v/t
delta
∆v = vf - vi
SI unit for distance
meter
SI unit for time
seconds
Graph: distance vs. time (slope)
slope = velocity
Graph: velocity (speed) vs. time (slope)
slope = acceleration
On a speed vs. time graph, constant acceleration is represented by...
