Kinematics The Study of Motion

Scalar and vector I drove 125 kms and reached my destination I drove 125 kms south and reached my destination

Scalars Described by their magnitude only ex. distance(d) = 5 km speed(v) = 20ft/s mass(m) = 0.56 g time(t) = 3.7 s

Vector quantities are described by both their magnitude and direction ex. displacement (d) =5km [north] velocity (v) = 20ft/s [NW] force (F) = 340N [fwd]

distance and displacement distance - how far an object has travelled from its original position displacement - how far away an object is from its original position

How is the butterfly’s distance different than its displacement?

What is the skiers distance and displacement at t=1min, t=2 min and t=3 min?

Graphing time and position What does the graph tell us about the objects movement?

How are these two graphs different How are these two graphs different? What do they tell us about how the motion is different?
