14 Objectives I will identify the relationship between motion and a reference point I will identify the two factors that speed depends on I will determine the difference between speed and velocity I will analyze the relationship of velocity to acceleration I will interpret a graph showing acceleration

15 Key Terms Motion Distance Displacement Instantaneous speed Constant speed Speed Velocity Acceleration

16 Essential Question Are distance and time important when describing motion?

17 Describing Motion Motion: occurs when an object changes position relative to a reference point Distance v. Displacement Distance- how far an object has traveled Displacement- distance and direction of an object change in position from starting point Speed- the distance an object travels per unit time rate of change on position Average (avg) speed (v) = total distance (d)/ total time (t) v=d/t

18 Types of Speed Type of Speed Description Example Instantaneous speed of any given point in time driving a car and looking down at the speedometer Average total distance traveled divided by total time taking a road trip Constant speed that does not vary putting a car in cruise control

19 Let s Try a Problem If you take a walk for 1.5 hours and travel 7.5 km, what is your average speed?

20 Graphing Motion Motion of an object can be plotted on a distance - time graph x axis- time y axis- distance The slope of a line on a distance - time graph gives the speed of an object in motion

23 Measuring Motion Day 3

24 Essential Question What is the difference between positive and negative acceleration?

25 Acceleration Velocity- includes speed of an object and the direction of its motion Question: what is the difference between speed & velocity? Velocity includes direction whereas speed does not. Acceleration- rate of change of velocity. acceleration occurs when an object changes speed, its direction, or both.

26 Calculating Acceleration Note: Change in velocity = final velocity - initial velocity acceleration formula = a=vf-vi/t

27 Acceleration Positive Acceleration A plane takes off Final Velocity = 80 m/s Initial Velocity = 0 m/s Time= 20 s Negative Acceleration A bike comes to a stop Final velocity = 0 m/s Initial velocity = 3 m/s Time = 2s

28 Practice Problems: Acceleration

Acceleration. 3. Changing Direction occurs when the velocity and acceleration are neither parallel nor anti-parallel Acceleration When the velocity of an object changes, we say that the object is accelerating. This acceleration can take one of three forms: 1. Speeding Up occurs when the object s velocity and acceleration
