tell me the two different kind of forces
contact and non contact forces
tell me the general properties of matter
mass and volume
tell me two natural materials
wood and wool
heavy
light
specific properties of matter
flexibility, resistance, hardness and thermal conductivity
tell me 3 examples of contact forces
pulling or pushing somethig, changing direction of an objet or changing speed
how do you measure mass?
with a balance or scale
tell me 3 man made materials
plastic, paper and glass
opaque
if an object is easy to bend or not
what is a force?
a force is a push or pull of an object

soft
hardness is
if an object is easy to scratch or not
Tell me an example of a non - contact force
magnets or gravity
what is density?
the relationship between mass and volume
what materials are good for clothes?

elastic
rigid
resistance is
if an object is easy to break or not
explain a situation in which a contact force is used
free answer
the one with a bigger mass
tell me the properties we have learnt for materials
impermeability, elasticity, transparency and strenght
impermeable
permeable
thermal conductivity is
if an object transmits the heat or not
