1D Motion

What’s your frame of reference?


Frames of reference

Frames of reference

From where are you measuring?


Frames of reference1

Frames of Reference

  • Location of the Point of Reference

  • Measurements are relative

  • Standards of Measurement

  • Unit Conversions


Distance vs displacement

Distance vs Displacement

How far? What direction?


Distance vs displacement1

Distance vs. Displacement

  • Total distance does not always equal total displacement

  • Distance measured in meters/kilometers

  • Displacement is measured in meters/kilometers with direction

  • Change in distance = Δd = df- di

  • Change in displacement = Δx = xf - xi


Scalar vs vector

Scalar vs. Vector

What is direction anyway?


Examples and definitions

Examples and Definitions


Speed vs velocity

Speed vs. Velocity

Who wins the tortoise or the hare?


Who wins between the tortoise and the hare

Who wins between the tortoise and the hare?

The tortoise is traveling at a velocity of 0.5 kmph to the north, while the hare is travel at a speed of 10 kmph. Who reaches the finish line first?


The answer is

The Answer is

  • It depends.

    • What direction is the hare traveling?

    • What direction is the finish line from the starting line?

    • Does the tortoise have a head start?

  • These are all parts to a frame of reference to determine a winner.


Speed vs velocity1

Speed vs. Velocity

  • Avg. Speed or speed is measured in kmph or kph

  • Speed = (Δ d/Δ t)

  • Scalar quanity

  • Ex: 30 kph

  • Avg. Velocity or velocity is measured in kmph or kph

  • Velocity = (Δx/Δ t)

  • Vector quantity

  • Ex: 30 kph to the north


Practice

Practice

  • What is the total displacement and total distance of a dump truck that travel a 30 km there and back trip to deliver a load of dirt?

  • What is the average speed of a car that traveled 1 km in 5 mins, 10 km in 15 mins, and 30 km in 30 mins?


Practice1

Practice

  • What is the avg. velocity

  • What is the average speed of a car that traveled 1 km in 5 mins, 10 km in 15 mins, and 30 km in 30 mins?
