|In order to describe the movement of objects,
we need to use vectors, a quantity or magnitude with a direction
associated with it.
Examples: 1) 30 km/h west 2) 20 cm up 3) 10 N force toward you
Scalars are any magnitudes with NO direction
associated with them.
Examples: 1) 64 Kg 2) 20 cm long 3) 10 m in the air
When studying how and where objects
move, vectors must be used, and in the following ways:
1) To describe an object's resultant magnitude
and direction of motion by the component vectors acting on it.
