resulting from the object's interaction with
another object
M. Evan Cendekia s

7. Spring force is a force that produce
from a spring, because the spring is
pulled or pressed
M. Evan Cendekia

8. Machine force is the force
generated by a given the machine.
M. Evan Cendekia s

9. Muscular force is a force that
comes from muscular power.
M. Evan Cendekia s

10. Spring force is a force that produce
from a spring, because the spring is
pulled or pressed

force produced by
magnets.

15.  1. Frictional Force : car can move
 2. Machine Force : can produce electrical (
Diesel Engine)
 3. Muscular Force : People can push the car
 4. Spring Force : People can hunt with
spring force ( use arrow )
 Air resistance Force : wind can play windmill
that can regenerate energy
 5. Electrical force : the lamp will be light
 6. Gravitational Force : reflected basketball will
not bounce too high so basketball players no trouble
catching the ball
 7. magnetic force : can collect nails in the
street
M. Evan Cendekia s

16.  1. Frictional Force : friction car with other
cars
 2. Machine Force : machines produce
waste
 3. Muscular Force : fight causes pain in the
body
 4. Spring Force : people use arrow to kill
rare animal
 Air resistance Force : can make a tornado
 5. Electrical force : can kill people
 6. Gravitational Force : meteor that across the
atmosphere will pulled into earth by gravitation
 7. magnetic force : tv will be chance color

17.  Several force acting on the body in one work
line can be replaced by a force called force
resultant
 Mathematically, the magnitude of force
resultant (R) is expressed as follows :
R F1 F2 F3
M. Evan Cendekia s

18.  Weight of a body can change depends on the
magnitude of gravitational force.
 Weight of the body is earth gravitational
force acting on the body.
 Weight of a body can change depends on
the magnitude of gravitational force.
 The weight unit is states with force unit,
namely newton (N)
M. Evan Cendekia s

19.  “every body will be at rest or move in uniform
rectilinear if there is no forces change that
condition.”
 “ if force resultant acting on the body is equal
to zero, or there is no forces acting on the body,
the body will be at rest ( does not move ) or
will move in uniform rectilinear”
F 0
M. Evan Cendekia s

20.  “The body that influence force will have
acceleration which its magnitude is directly
proportional to the magnitude of the sum of
force and inversely proportional to its mass”
F
a /F m.a
m
M. Evan Cendekia s

21.  “If a body makes force ( making action ) to
another body, apears reaction force from the
body to the former body with equal
magnitudes, while the directions are in
opposite”
