Homework: the low of levers science 6 primary second term

put true or false
when the arm of force is larger than the arm of resistance then the effort force is less than the resistance force

put true or false
when the effort arm is longer than the resistance arm , the lever save effort

put true or false
Newton is the measuring unit of resistance and effort force

put true or false
the distance between the resistance force and the fulcrum is called resistance arm

put true or false
the distance between the effort force and the fulcrum is called effort arm

put true or false
the effort force is measured in kilogram

put true or false
the first class levers always save effort

put true or false
the resistance arm is measured in meter

put true or false
the first class levers never save effort

put true or false
the second class levers some times save effort

choose
the force arm is sometimes equal to the resistance arm in the
class

put true or false
resistance arm is measured in centimetre

choose
the lever save effort when
( - -- )

put true or false
the distance between the effort force and the fulcrum is called the arm of force

put true or false
the arm of force is always longer than the arm of resistance in the first class levers

choose
when the arm of the force is longer than the arm of resistance the effort forces
