Question 8

Describe the relative motion of an object using a particular frame of reference

Answer 8

• The jetplane is in motion relative to the ground
• The jet plane is not moving or stationary relative to the passengers on the
• The jetplane is not moving or stationary relative to a plane flying directly next to it at the same speed

Question 9

Define speed

-units

Answer 9

How quickly or slowly something changes position in a given amount of time
S=d/t
m/s. cm/s. km/hr

Question 10

Solve speed problems

Answer 10

S=D/T 
Magic triangle.    D
                         S  x  T 
T=D/S
D=SxT

Question 11

Distance. Time

Question 12

Straight diagonal line on a distance- time graph

Answer 12

Constant speed

Question 13

Answer 14

Increasing speed

Question 15

Downward slope on a distance- time graph

Answer 15

Decreasing speed

Question 16

Define and be able to describe examples of vectors

Answer 16

A quantity that has both size and direction

The car is going 50 m/hr north

Question 17

Define velocity

-units

Answer 17

Speed in a specific direction

m/s. cm/s. km/hr

Question 18

Compare speed and velocity

Answer 18

Both involve distance and time

Use the same units. Ex- m/s

Question 19

Difference between speed and velocity

Answer 19

Velocity is a vector

Velocity uses direction

Question 20

Explain the relationship between velocity and acceleration

Answer 20

In final velocity subtracted for the initial velocity over the change in time will give acceleration

Question 21

Define acceleration

- units

Answer 21

How quickly something's velocity changes over time
m/s/s.   m/s2.       cm/s/hr
A=vf-vi
    ------
     ⚠️T

Question 22

Describe and interpret velocity- time graph

Answer 22

How fast or slow something goes in a certain direction over a given amount of time

Question 23

Straight diagonal line on a velocity- time graph

Answer 23

Increasing speed

Accelerating

Question 24

A straight flat, horizontal line on a velocity- time graphs

Answer 24

Constant speed

Question 25

An upward slope on a velocity- time graph

Answer 25

Accelerating Increasing speed Accelerating faster

Question 26

A downward slope on a velocity- time graph

Answer 26

Deceleration Decreasing speed Going slower

Question 27

Why is it important to know velocity rather than just speed

Answer 27

So you can know the direction as well rather than just how fast or slow it is going

Question 28

If an object is moving at a constant speed, can it be accelerating?

Answer 28

Yes, because acceleration occurs when you change speed or direction. So you can be going the same speed but change direction.

Question 29

What are some examples of acceleration?

Answer 29

1. Increase 2. Decrease 3. Direction 4. A car going north 5. A train that is coming to a stop 6. On a roller coaster when it is picking up speed going down the hill

Question 30

At what speed did a plane fly if it traveled from 1760meters in 8 seconds?

Answer 30

S=S S=d/t D= 1760m 1760m T= 8s ------ 8s S=220 m/s

Question 31

An airplane, starting from rest accelerates to a velocity of 30 m/s in 15 seconds. What is the acceleration of the airplane?

Answer 31

A=A A=vf-vi VI= 0 m/s ------- VF= 30 m/s ⚠️T T= 15s A= 30m/s- 0m/s -------------- 15s A= 2m/s/s

Question 32

A= 10m/s - 5m/s --------------- 5s

Answer 32

A=1m/s/s

Question 33

Find vf. .5m/s/s= vf - 0m/s ----------- 20s

Answer 33

Cross multiply .5m/s/s vf --------- ---- 1s 20s A= 10m/s

Question 34

Calculate the average speed of a car that has traveled from 125 miles to 320 miles in 3 hours.

Answer 34

S=S S=D/T D= 320 -125= 195mi S= 195mi T= 3hr --------- 3hr S= 65mi/hr
