Acceleration Animation

Question 1

1 . Velocity is the measurement of both the [blank_start]speed[blank_end] and the [blank_start]direction[blank_end] of an object
2 . [blank_start]Acceleration[blank_end] is the rate at which an object changes its speed.

3 . The green and purple arrows represent [blank_start]vectors[blank_end].
4 . The green arrow represents the [blank_start]speed[blank_end] of the car .
5 . The longer the green arrow the [blank_start]faster[blank_end] the car is moving .
6 . The [blank_start]direction[blank_end] of the arrow shows where the car is headed .
7 . The length of the purple arrow indicates how quickly the car is [blank_start]accelerating[blank_end].
8 . Two ways a car can accelerate is :
[blank_start]Speeding[blank_end] up
[blank_start]Slowing[blank_end] down
Changing [blank_start]Direction[blank_end]
9 . If purple arrow points in the same direction as velocity ( speed ) arrow then speed is [blank_start]speeding[blank_end] [blank_start]up[blank_end].
10 . If purple arrow points in opposite direction then speed is [blank_start]slowing[blank_end].
11 . If the arrow points in between then car is changing [blank_start]changing[blank_end] [blank_start]direction[blank_end].

Question 2

The [blank_start]horizontal[blank_end] line on a speed vs . time graph means the car is traveling at a [blank_start]constant[blank_end] speed . . . .
If the line slants [blank_start]up[blank_end] the speed is [blank_start]increasing[blank_end], is line slants [blank_start]downward[blank_end] then speed is [blank_start]decreasing[blank_end].
