difference between temperature and heat

temperature is a how you meassured it and heat is the energy

1 heat equal as …. joule?

4,2 joule or 1 joule = 0,24 heat

termometer scale language (4)

celcius, reamur, farenheit, kelvin

celcius : reamur : farenheit : kelvin (C F R K)

100 : 180 : 80 : 100

heat formula

Q = mcdeltaT

Q at heat formula stating

heat amount

m at heat formula stating

object mass (kg)

c at heat formula stating

heat spesific eg J/kg or kal/kg

delta T at heat formula stating

temperature rise (end temperature - early temperature) (K/ 'C)

heat release and absorb formula

Q absorb equal to Q release (m1c1(T-T1) = m2c2(T2-T))

1Kilojoule equal to … joule

1000 (thousand)

L at heat formula stating

melting heat (J/kg)

L formula

L = Q/m

motion formula

V:s/t

v at motion formula stating

speed (m/s)

s at motion formula stating

distance(m)

t at motion formula stating

time (t)

touchless force formula (gravity)

w = m*g

w at touchless force stating

object mass w/ gravity (kgm/s^2 =N)

m at touchless force stating

object mass (kg)

g at touchless force stating

gravity (9,8 m/s)

newton first law of motion

An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force

newton second law of motion

The acceleration of the body is directly proportional to the net force acting on the body and inversely proportional to the mass of the body

newton third law of motion

If the first object exerts an action force on the second object, the second object exerts a reaction force on the first object that is the same in magnitude but in the opposite direction.

motion law formation

F=ma

F at motion law stating

Force (N)/dyne

m at motion law stating

object mass (kg)

a at motion law stating

object acceleration (m/s)

newton third law formation

F action equal to F reaction
