Chapter 3 Flashcards
What is the big five uniform acceleration equations?
- d=1/2(Vo + V)
- V= Vo + at
- d= Vot + 1/2at^2
- d=vt -1/2at^2
- V^2= Vo^2 + 2ad
What is the equation used for displacement in the horizontal direction when dealing with projectiles?
X= Vo(x)t

What is the value for kilo (k)?
10^3
What is the value for mega (M)?
10^6
What is the value for giga (G)?
10^9
__________ is how fast velocity changes, an object velocity changes if the speed or direction changes
Accleration
Can an object be accelerating if its velocity is constant?
Yes because if it has the same speed but changes direction its accelerating
If acceleration is perpendicular to the velocity what does that mean?
Means that the object speed is constant
If acceleration is from 0 to 90 degree of velocity what does that mean?
Means that an object speed is increasing and its direction is changing
When acceleration is between 90 to 180 degrees what does that mean?
Means that the object speed is decreasing and changing directions
