Suzette’s Sprint to Science

It is now 8:59 am, but when the bell rings at 9:00 am Suzette will be late for Science class for the third time this week. She must get from one side of the school to the other by hurrying down three different hallways. She runs down the first hallway, a distance of 35.0 m, at a speed of 3.50 m/s. The second hallway is filled with students, and she covers its 48.0 m length at an average speed of 1.20 m/s. The final hallway is empty, and Suzette spring its 60.0 m length at a speed of 5.00 m/s

Chapter Summary

Frame of ReferenceA frame of reference is necessary to

describe motion accuratelyFoR is a system of objects not

moving with respect to one anotherRelative motion describes movement

from different FoRs Ex: Looking at someone sitting next to

you in a car vs. someone standing on the street corner watching the car vs. the billboard across the street

Distance vs D isp lacementDistance is the total length of

the path between two pointsDisplacement is a vector

describing the ending point compared to the starting point. It includes: The direction from starting point The length of a straight line from

the starting point to the ending point

The SI unit for length is the meter (m)

Solve…1. A caterpillar travels 5 m east, 2 m

north, 7 meters west, and 3 m south.  a. What is the caterpillar’s total distance?  b. What is the caterpillar’s displacement?

2. A science textbook is moved once around the perimeter of a table that is 1m by 2m and ends up in its initial position.a. What is the books total distance?b. What is the book’s displacement?

Average Speed Speed is the change in distance

divided by the change in timeV= D

T Variations of the formula

T= D and D=V x T V

Units of SPEED and VELOCITY are m/s

The SI unit for time is second (s) Instantaneous Speed is how fast a

speed is changing at a specific instant (speedometer)

VelocityVelocity is a vector.To describe a vector you must have both a magnitude (some kind of number) and a direction Ex : 5 m south, 10 km left, 2 inches forward

Circular paths experience a continuous change in velocity because the direction is constantly changing

Velocity Combine velocities by vector addition If both are in the same direction

ADD If they are in different directions

SUBTRACT

Tailwind

Solve…1. A runner completes a 10.0 km race in

exactly 30 minutes. A. What is the runner’s average speed in

km/min?B. What is the runner’s average speed in km/hr?

2. When the outdoor emergency warning siren at Cheryl’s school was tested, the sound from the siren took 7 s to reach her house located 2.4 km from the school. What is the speed of the sound of the siren in m/s?

Graphs

Distance Time graphs show speed (m/s) and are linear graphs.

The slope of the line (rise/run) is the speed

A Speed Time graph shows acceleration (m/s2)

Nonlinear (curved) graphs show changing acceleration

Graphs

Section 11.2

Acceleration Acceleration is ANY change in speed

or direction (any change in velocity) Acceleration can be positive

(speeding up) Or negative (slowing down) Or a result of changing direction

(turning) Instantaneous Acceleration is how

fast a velocity is changing at a specific instant

AccelerationAcceleration is the change in velocity divided by the change in timea = (Vf – Vi)

TUnits of Acceleration are m/s2

Acceleration of Gravity (Free Fall) is 9.8 m/s2

Solve…

1. An elevator is moving upward with a speed of 11 m/s. Three seconds later, the elevator is still moving upward but its speed has been reduced to 5 m/s. What is the elevator’s acceleration?

2. A plane starts to take off from a runway at 70 km/hr. It take the plane 30 seconds to get to that speed. What is the plane’s acceleration?

 a. What is the Girl Scout’s total distance?  b. What is the Girl Scout’s displacement from

her home?  

 2. Average Speed What is the average speed of a

helicopter that flies 50 km in 20 minutes and then 30 km in 10 minutes?

   3. Acceleration An elevator is moving upward with a

speed of 16m/s. Four seconds later, the elevator stops on the sixteenth floor. What was the elevator’s acceleration?
