9.2 Flashcards
1
Q
velocity-time graph
A
represents the motion of an object with changing velocity
2
Q
Slope
A
Rise / run
3
Q
average acceleration
A
A= V/t
4
Q
air resistance,
A
a friction-like force. That is why everthing doesn’t fall from the sky at the same speed. The air resistance is always different.
5
Q
acceleration due to gravity (g)
A
In the absence of air resistance, all objects, regardless of their mass, fall with the same constant acceleration of 9.82 m/s2 downward. g = 9.8 m/s2, downward.
6
Q
gravity
A
s attracted downward by the force of
7
Q
A velocity-time graph
A
provides information
about the object’s velocity and acceleration.
