(9 cards)
1
Q
Hooke’s Law
A
Extension of spring is directly proportional to force applied to it.
2
Q
Equation for density
A
Density(kg/m3) = Mass(kg)/Volume(m3)
3
Q
Arrangement of particles in solid
A
High density, vibrating against one another
4
Q
Arrangement of particles in gas
A
Spread far apart, moving very rapidly
5
Q
Arrangement of particles in liquid
A
Medium density, no arrangement, move slowly,
6
Q
Density of water
A
1000kg/m3
7
Q
Equation for pressure
A
Pressure(Pa) = Force(N)/Area(m2)
8
Q
Equation for pressure in liquids
A
Pressure(Pa) = Depth x Density(kg/m3) x Gravitational Field Strength(N/Kg)
9
Q
Gravitational Field Strength for Earth
A
10N/Kg
