MOTION & POSITION

motion – a change in an object’s position relative to a reference point

Page 3: Motion IPC NOTES. MOTION & POSITION motion – a change in an object’s position relative to a reference point.

DISTANCE VS. DISPLACEMENT

distance – the total length traveled

displacement – the distance and direction of an object’s change in position

Page 4: Motion IPC NOTES. MOTION & POSITION motion – a change in an object’s position relative to a reference point.

DISTANCE VS. DISPLACEMENT

Billy runs 2 full laps around the track. If each lap is 400 m, what is his total distance traveled?

Page 5: Motion IPC NOTES. MOTION & POSITION motion – a change in an object’s position relative to a reference point.

DISTANCE VS. DISPLACEMENT

Billy runs 2 full laps around the track. If each lap is 400 m, what is his total distance traveled?

distance = 800 m

DISTANCE VS. DISPLACEMENT

Billy runs 2 full laps around the track. If each lap is 400 m, what is his displacement?

displacement = 0 m

SPEED

speed – the distance an object travels per unit time

There are 3 types of speed: constant, average & instantaneous

Page 9: Motion IPC NOTES. MOTION & POSITION motion – a change in an object’s position relative to a reference point.

SPEED

constant speed – speed that does not change over time

ex) driving with cruise control

Page 10: Motion IPC NOTES. MOTION & POSITION motion – a change in an object’s position relative to a reference point.

SPEED

average speed – the total distance traveled divided by the total time traveled

ex) average speed for a trip

Page 11: Motion IPC NOTES. MOTION & POSITION motion – a change in an object’s position relative to a reference point.

SPEED

instantaneous speed – the speed at an exact moment

ex) the speed listed on a speeding ticket

GRAPHING DISTANCE VS. TIME

Graphing distance vs. time shows velocity.

Time = independent variable = X-axis

Distance = dependent variable = Y-axis

GRAPHING DISTANCE VS. TIME

What is the total distance traveled at 30s?

Page 15: Motion IPC NOTES. MOTION & POSITION motion – a change in an object’s position relative to a reference point.

GRAPHING DISTANCE VS. TIME

How long did it take to travel 80m?

Page 16: Motion IPC NOTES. MOTION & POSITION motion – a change in an object’s position relative to a reference point.

GRAPHING DISTANCE VS. TIME

What is happening between 20s and 48s?

Page 17: Motion IPC NOTES. MOTION & POSITION motion – a change in an object’s position relative to a reference point.

CALCULATING SPEED & VELOCITY

V = d

t

Page 18: Motion IPC NOTES. MOTION & POSITION motion – a change in an object’s position relative to a reference point.

CALCULATING SPEED & VELOCITY

V = d

t

V = velocity or speed (m/s)

d = distance (m)

t = time (s)
