Acceleration Flashcards
1
Q
What is acceleration and is it a vector or scalar quantity?
A
How fast the velocity is changing - is a vector quantity
2
Q
Unit used to measure acceleration
A
m/s² (metres per second per second)
3
Q
Formula to calculate acceleration
A
change in velocity divided by time taken or v-u/t
4
Q
Deceleration
A
The opposite of acceleration - causes object to get slower
5
Q
Formula to relate acceleration to initial velocity, final velocity and distance
A
Final velocity² - initial velocity² = 2 x acceleration x distance or v² - u² = 2ax
6
Q
Term to describe acceleration towards the Earth
A
Acceleration due to gravity
7
Q
Value of the acceleration towards the Earth
A
9.8 m/s², rounded off to 10 m/s²
