1D Motion What’s your frame of reference?

Frames of reference From where are you measuring?

Frames of Reference Location of the Point of Reference Measurements are relative Standards of Measurement Unit Conversions

Distance vs Displacement How far? What direction?

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 = Δ d = d f - d i Change in displacement = Δ x = x f - x i

Scalar vs. Vector What is direction anyway?

Examples and Definitions

Speed vs. Velocity Who wins the tortoise or 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 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. 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 = ( Δ x/ Δ t) Vector quantity Ex: 30 kph to the north

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?

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?
