Equations Flashcards
1
Q
Speed =
A
distance / time taken
2
Q
Acceleration =
A
change in velocity / time taken
OR
a = v-u / t
3
Q
Equation for final velocity
A
v^2 - u^2 = 2ax
4
Q
Weight =
A
mass x gravitational field strength
5
Q
Mass =
A
weight / gravitational field strength
6
Q
Resultant force =
A
forces in one direction + forces in same direction
OR
forces in one direction - forces in the opposite direction
7
Q
Force =
A
mass x acceleration
8
Q
Acceleration =
A
change in speed / time taken
9
Q
Momentum =
A
mass x velocity
10
Q
change in momentum =
A
mv - mu
11
Q
Force =
A
Change in momentum / time
12
Q
Stopping distance =
A
thinking distance + braking distance
13
Q
Work done =
A
force x distance moved in the direction
14
Q
Kinetic energy =
A
0.5 x mass x speed^2
15
Q
Magnification =
A
size of image / actual size of specimen
