MOTION

Mechanics- the study of motion and its effects Kinematics- description of the motion.(fast, slow, speeding up, straight, curved) Dynamics- The cause and effect of the motion. (force, momentum, energy, power)

POINT OF REFERENCE- A stationary object to compare a moving object to. DISTANCE- How far something travels (meters) DISPLACEMENT- How far something is from its starting point (meters). How far did the person walk? What is their displacement? 2m

SCALAR VS. VECTOR SCALAR – has magnitude only (85mph, 50 ⁰c) VECTOR- defined by magnitude and direction ( 23m/s north, 16ft southwest) Magnitude is the numerical value

v = d/t unit: m/s SPEED – distance traveled over time. speed = distance/time VELOCITY- Change in displacement over time average velocity = displacement/time v = d/t unit: m/s

A car travels east 10km in 30 minutes A car travels east 10km in 30 minutes. They turn back and travel 3km west in 10 minutes. What is the speed of the car in km/min and m/s? speed = distance / time speed = 13km/ 40 minutes speed= .325km/min speed = .325 km/min X 1000/60 speed = 5.42m/s

Same example What is the average velocity of the car in km/min and m/s? velocity = displacement/ time v= 10km+ -3km = 7km / 40min 40min v= 0.175 km/min v= 0.175km/min x 1000 /60 v= 2.92 m/s East
