Linear motion Flashcards
1
Q
What is linear motion?
A
Movement of a body in a straight or curved line, where all parts of the body move the same distance in the same direction
2
Q
What is an example of Linear motion
A
The luge as all parts of body do the same
3
Q
What are the 6 descriptors?
A
- Distance
- Displacement
- Speed
- Velocity
- Acceleration
- Deceleration
4
Q
Distance =
A
Area covered from A to B, measured in metres
5
Q
Displacement =
A
Shortest area from A to B, in metres
6
Q
Velocity
A
Rate of change of distance, measured in M/S
7
Q
Acceleration
A
Rate of change in velocity, measured in M/S/S
Acceleration (M/S/S) = (final velocity - initial velocity (m/s) / time taken (s))
8
Q
Deceleration
A
Negative rate change in velocity, measured in M/S/S.
9
Q
Speed
A
Rate of change in distance, measured in meters per second m/s.
Speed (m/s) = distance (m) / time (s)
