Flashcards in Motion Deck (24):
1

Speed

How fast an object is moving = D/T

2

Velocity

An objects speed and direction =D/T

3

Acceleration

Changing velocites

4

Positive Acceleration

Speeding up

5

Negative Acceleration

Slowing down

6

Reference Point

A location or object that is being used to compare another objects motion

7

What type of motion does this show?

Q image thumb

Backwards constant velocity

 

the distance is decreasing from 3 to 0

8

What type of motion does this show?

Q image thumb

Constant Speed or Constant Velocity

9

What type of motion does this show?

Q image thumb

Speeding up

10

What type of motion does this show?

Q image thumb

Constant Speed or Constant Velocity

11

What type of motion does this show?

Q image thumb

Not moving

 

The distance stays at 3 m the entire time

12

What type of motion does this show?

Q image thumb

Slowing down

 

The slope of the line starts high (fast motion) then flattents out (slow motion)

13

What type of motion does this show?

Q image thumb

Constant Velocity

The velocity of the line is always 5 m/s

14

What type of motion does this show?

Q image thumb

Not Moving

 

Velocity is always zero

15

What type of motion does this show?

Q image thumb

Decreasing Velocity or Slowing Down

V starts at 5 and decreases to 0

16

Assume these are all Velocity vs Time graphs.  Which shows backwards motion?

Q image thumb

Graph D

it shows a negative velocity which is backwards motion

17

What type of motion does this show?

Q image thumb

Increasing Velocity or Speeding UP

V starts at 0 and decreases to 10

You are on a train taveling at 10 m/s to the north with the ground as the reference point. You are seated next to your best friend.  How fast are you moving compared to your friend?

0 m/s

19

You are on a train taveling at 10 m/s to the north with the ground as the reference point. You you walk to the front of the train at 2 m/s.  How fast are you moving compared to the ground?

12 m/s north

20

You are on a train taveling at 10 m/s to the north with the ground as the reference point. You you walk to the front of the train at 4 m/s.  How fast are you moving compared to the ground?

14 m/s North

21

You are on a train taveling at 10 m/s to the north with the ground as the reference point. You you walk to the back of the train at 2 m/s.  How fast are you moving compared to the ground?

8 m/s north

22

You are on a train taveling at 10 m/s to the north with the ground as the reference point. You you walk to the back of the train at 7 m/s.  How fast are you moving compared to the ground?

3 m/s north

23

You are on a train taveling at 10 m/s to the north with the ground as the reference point. You you walk to the back of the train at 12 m/s.  How fast are you moving compared to the ground?

2 m/s south

24

You are seated on a train taveling at 10 m/s to the north with the ground as the reference point. Your friend is seated on a train headed south on the same track at 15 m/s.  How fast is your friend moving with you as the reference point?

25 m/s south
