Forces & Force Vectors
- Force Vectors: Force vectors are a different way of measuring distances.
- The picture to the right depicts a force vector.
Force vectors are drawn like arrows, from a
starting point, to an ending point. The length
and direction of the vector matter - force
vector drawings have to be to scale or they
are incorrect.
- A Force Vector may represent anything that has magnitude (size) and direction. In order to represent a
force as a vector, you draw an arrow with the length proportional to the force (eg 1cm = 10N) and the
direction the same as the actual direction of the force. For example, in the picture of the force vector to
the right, there is depicted a force of 30N acting at an angle of 45 Degrees, so you could draw a 3cm long
line at a 45 Degree angle.
- Non-Concurrent Coplanar Forces: This means that all the forces acting on an object are
acting in different directions but all on the same plane:
- Concurrent forces: this means that all of the forces on an object are acting on one
point as shown in the picture below: (All of the forces are acting directly inwards and
towards the center of the cube.)
- Coplanar Forces: This means that all of the forces acting on an
object are on the same plane.
