CP1 Flashcards
Relation of:
-Speed
-Distance
-Time
Speed = Distance/Time
s = d/t
Speed measurement
m/s (metres per second)
Distance measurement
m (metres)
Time measurement
s (seconds)
Relation of:
- Acceleration
-Final velocity
-Initial velocity
-Time
Acceleration = final velocity - initial velocity/time
a=v-u/t
Acceleration measurement
m/s^2 (metres per second squared)
Final velocity measurement
m/s (metres per second)
Initial velocity measurement
m/s (metres per second)
Relation of:
-Weight
-Mass
-Gravitational Field Strength (GFS)
Weight = Mass x GFS
w = mg
Weight measurement
N (Newtons)
Mass measurement
kg (kilograms)
GFS measurement
N/kg (Newtons per kilogram)
What is the GFS on Earth?
10N/kg
Relation of:
-Acceleration
-Final velocity
-Initial velocity
-Distance
Final velocity squared - Initial velocity squared = 2 x acceleration x distance
v^2 - u^2 = 2ax
ONLY IN THIS EQUATION IS DISTANCE REPRESENTED BY X.
What is a scalar quantity?
A scalar quantity has a size but no direction
