motion - Coggle Diagram
motion
forces
mass and weight
weight as gravitational force
gravitational field strength
mass a quantity of matter
effect of gravity on mass
distinguish between mass and weight
effect of forces
change size,shape and motion
air resistance/drag
friction
upthrust
resultant forces
find resultant
forces acting along same line
force calculations
newtons second law
force= mass x acceleration
springs
extension of spring
hooke law
stretching springs
limit of porprotionality
motion concepts
acceleration
deceleration as negative
speed-time graphs
define and calculate
finding from speed-time graphs
understand acceleration
scalar and vector quantities
ex: mass,energy,temperature
ex: force, weight, acceleration (vector)
distinguish between scalar and vector quantities
speed
define speed
calculate average speed
distance-time speed
finding from distance-time graphs
turning forces
moment of force
effect of a force causing rotation
moment = force x perpendicular distance
equilibrum
principle of moments
anticlockwise vs clockwise moments
conditions for an object in equilibrum
stability and centre of gravity
effect on stability
stable vc unstable object
centre of gravity location
measurements
length,volume and time
making multiple
measuring short interval
units
density
determine
density of irregular shaped solids
calculate
density of liquid
relate pressure to force and area
calculating pressure
pressure = force/area
