What force opposes motion?
friction
the apparent shift in the position of an object when viewed from different angles, which can lead to inaccuracies in measurement.
parallax error
10^-9 m / 0.000000001 metres.
nanometre
10^9 m or 1,000,000,000 (1 billion) metres
gigametre
error introduced by the system (associated with faulty equipment or flawed experimental design)
systematic error
Has magnitude (size) only and no direction.
Scalar quantity
Has both magnitude and direction.
vector quantity
The resultant force of two forces acting at right angles to each other can be calculated by using the
Pythagorean theorem
the direction of two forces acting at right angles to each other can be calculated by
tan theta = Fy/Fx
