Phabulous Physics: Vectors Physics Topics Vectors

Phabulous Physics: Vectors Vectors  A vector is a quantity that involves both magnitude and direction. – 55 mph north – A downward force of 3 Newtons  A scalar is a quantity that does not involve direction. – 55 mph – 18 cm long

Phabulous Physics: Vectors Vector Notation  Vectors are often identified with arrows in graphics and labeled as follows: A Vector A represents motion 10 cm to the right. AA XYZ 

Phabulous Physics: Vectors Displacement  Displacement is an object’s change in position. Distance is the total length of space traversed by an object. 5m 3m 1m  mmmm mmm 9135 Distance 7.636ntDisplaceme 22   6.7m Start Finish = 500 m m m 005 Distance 0 Displacement  
