Slide 1

Kinematics

The Study of Motion

Slide 2

I drove 125 kms and reached my destination

I drove 125 kms south and reached my destination

Slide 3

Described by their magnitude only

ex. distance(d) = 5 km

speed(v) = 20ft/s

mass(m) = 0.56 g

time(t) = 3.7 s

Slide 4

quantities are described by both their magnitude and direction

ex. displacement (d) =5km [north]

velocity (v) = 20ft/s [NW]

force (F) = 340N [fwd]

Slide 5

distance - how far an object has travelled from its original position

displacement - how far away an object is from its original position

Slide 6

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

Slide 7

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

Slide 8

What does the graph tell us about the objects movement?

Slide 9

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