Motion Graphs Flashcards
1
Q
Instantaneous Speed
A
The speed at a single point in time (car speed cameras) record instantaneous speed
2
Q
Average Speed
A
total distance / total time
3
Q
Gradient on d/t graph
A
Speed of the object
4
Q
Steep constant gradient (d/t)
A
Fast constant speed
5
Q
Shallow constant gradient (d/t)
A
Gentle constant speed
6
Q
Zero Gradient (d/t)
A
Stationary
7
Q
Increasing gradient (d/t)
A
Acceleration
8
Q
Decreasing gradient (d/t)
A
Deceleration
9
Q
Gradient on v/t graph
A
Acceleration
10
Q
Steep constant gradient (v/t)
A
Fast constant acceleration
11
Q
Shallow constant gradient
A
Gentle constant acceleration
12
Q
Zero gradient
A
No acceleration → constant speed
13
Q
Negative gradient
A
Deceleration
14
Q
Distance Travelled
A
Area under v/t graph
15
Q
Benefits of using light gates
A
Remove human reaction times from measuring time → much smaller uncertainty
