Lesson 3 Unit 1 Acceleration Flashcards
1
Q
What is acceleration?
A
Acceleration is a measure of how much the velocity of an object changes per unit time (m/s2)
2
Q
How does an object’s acceleration change?
A
when the velocity changes due to, increasing speed, decreasing speed, or change of direction
3
Q
How do you show change in acceleration
A
when it slows down, the velocity arrow and the acceleration arrow point in opposite direction, when it speeds up, they point in the same direction.
4
Q
Acc equation
A
a = vf - vi / t
5
Q
What does a speed time graph show
A
-Shows how speed changes over time
-time on x axis and speed on y axis
