Physics equations and the things behind them
- density(kg/m³)=mass(kg)/volume (m³)
- it does not vary with shape or size
- what it is made up of
- determines if it floats or sinks
- experiments
- you can measure it in solids or liquids
- you can use a measuring cylinder to measure liquid density
- 1ml = 1cm³ then use the mass to calculate it
- 1ml = 1cm³ then use the mass to calculate it
- solid cuboid
- measure length width height and multiply together
- measure length width height and multiply together
- solid cylinder
- diameter of circles at the bass halve to get r
- volume=π X r² X height
- volume=π X r² X height
- diameter of circles at the bass halve to get r
- eureka can
- fill up to just the spout
- the object you put in the can will displace the exact volume of itself so use 1ml = 1cm³
- repeat 3 times and figure out a mean before calculating
- repeat 3 times and figure out a mean before calculating
- the object you put in the can will displace the exact volume of itself so use 1ml = 1cm³
- let it drain before using the measuring cylinder
- thin string should be used to get the most accurate reading
- fill up to just the spout
- you can measure it in solids or liquids
- it does not vary with shape or size
- distance travled(m) = speed(m/s) X time(s)
- acceleration(m/s²) = change in velocity(m/s) / time(s)
- kinetic energy(j) = 0.5 X mass(kg) X (speed(m/s)²)
- moles = actual mass/ molar mass
