General physics Flashcards
1
Q
Velocity (m/s) =
A
distance(m) ÷ time(s)
2
Q
Acceleration =
A
final velocity-initial velocity ÷ time
3
Q
Weight (N) =
A
mass(kg) x acceleration due to gravity (m/s2)
4
Q
Density =
A
mass ÷ volume
5
Q
Force =
A
mass x acceleration
6
Q
Hooke´s law:
Force =
A
k(spring constant) x X(extension in m)
7
Q
Moment of force =
A
force x distance (from pivot)
8
Q
Work done =
A
force x distance (covered by an object)
9
Q
Kinetic energy (J) =
A
1/2 x mass (kg) x velocity2 (m/s)
10
Q
Potential Energy =
A
mass (kg) x acceleration due to gravity x height
11
Q
Power (W) =
Power (W) =
A
work done ÷ time taken
energy transfer ÷ time taken
12
Q
Pressure in pascal (Pa) =
A
force (N) ÷ area (m2)
13
Q
Pressure due to liquid =
A
density x acceleration due to gravity x height of liquid
