Vectors
- Scale Diagram
- Join all forces
together in a polygon
- The line to finish the
shape is the resultant
- Add arrows showing
the direction of the
force
- Join all forces
together in a polygon
- Parallelogram of Forces
- Only used with
two forces
- Make polygon using
the forces as sides
- Draw a line through the
middle, which is the resultant
- Only used with
two forces
- Vectors at Right Angles
- Use Pythagoras to find resultant
- Use Pythagoras to find resultant
- Vector = physical quantity
with direction and magnitude
e.g. displacement, velocity
- Scalar = physical quantity that is
not directional e.g. mass, energy
- Scalar = physical quantity that is
not directional e.g. mass, energy
- Resolving Forces
- Split one vector into two (diagonal into horizontal and vertical
- Represented as Fv and Fh
- The point of this:
- Vertical forces have
no effect horizontally
- Horizontal forces have
no effect vertically
- Can consider them
seperately if split
- Vertical forces have
no effect horizontally
- Split one vector into two (diagonal into horizontal and vertical
- Objects on a Slope
- Split the same way if on a slope
- Weight on object split into
two components (parallel
and perpendicular to slope)
- If object is in equilibrium
- Parallel component
equals friction
- Perpendicular
component equals
contact force
- Parallel component
equals friction
- Split the same way if on a slope
