Motion Time Problems Flashcards
1
Q
V(t) means
A
Velocity over time
2
Q
X(t) means
A
Position and how it changes over time
3
Q
A(t) means
A
Acceleration over time
4
Q
How do we convert A(t) to V(t)
A
Integrate
5
Q
∫Α(t) =
A
V(t)
6
Q
How do we convert V(t) to X(t)
A
Integrate
7
Q
∫V(t) =
A
X(t)
8
Q
How do we convert V(t) to A(t)
A
Differentiate
9
Q
V ’(t) =
A
A(t(
10
Q
X’(t) =
A
V(t)
11
Q
How do we find if speed is increasing at t=a?
A
Step 1. Find acceleration when t=a, and velocity when t=a
Step 2. If signs are Different, speed is Decreasing. If signs are the same , speed is increasing
12
Q
In a velocity time graph, area =
A
Distance
13
Q
In a velocity time graph, slope =
A
Acceleration
14
Q
In an position time graph, slope =
A
Velocity
15
Q
Speed is decreasing in a graph when
A
The line is sloping down
