force - Coggle Diagram
force
effefcts
start an object which is at rest
change the direction
stop the moving object
can change the speed of an object
change the shape and size
cannot change the mass of an object
contact
muscular
frictional
opposes the motion of an object
static
sliding
rolling
properties of friction
one surface is moved over the other
opposes the motion
nature of surface
rough surface- more friction
smooth surface less friction
depends on the mass of the body
more mass- more is the friction
non contact
at a distance
gravitational
magnetic
electrostatic
push/pull
newton(N)
force is physical cause that changes or tend to change the state of rest or the state of motion on object
