forces+gravity
the force of gravity on earth is 10m/s2
weigth of anything on earth
weight=mass x10
weight=60kg x 10m/s2
weight= 600 newtons
mass: amount of an object
sI unit=kg
measured using a mass baalnce
does not change depending where you are
weight:the force of gravity on an object
SI unit=newtons
measured using a newton meter
does change depending where you are (affect of gravity)
f=mxa
f=3kg x2m/2
f=6 newtons
contact force
something which comes into direct contact with the object to have an affect on it
example.pushing,pulling,squeezing
non contact force
something that does not have to coen into contact with the object to affect it
example: gravity
formula for force= F=mxa
force=mass x acceleration
define force
calculate force
physical world
identify friction and its effects
understand difference betwee mass and weight
investigate and graph the effect of force on a spring
force:anything that causes an object to move
calculate the force required to move 3kg mass to be accelerated by 2m per second(squarred)
balance and unbalanced forces acting on an object canceling eachother out
unbalanced forces will have an effect on the object
gravity: a pull to the centre of the earth!!
