Physics Unit 1 Part 1 Retake

Question 1

Distance

Answer 1

how far an object travels over a certain time interval
Ex: path on roads, gap

Question 2

Displacement

Answer 2

a straight line distance and direction between two positions
change in X

Question 3

Position

Answer 3

where an object is located, relative to a coordinate system (some arbituary reference point)
Ex: location, point, place

Question 4

Velocity (v)

Answer 4

tells you how fast and the direction

Question 5

Velocity average

Answer 5

change in x / change in t

Question 6

Speed

Answer 6

tells you how fast

Question 7

Speed average

Answer 7

total distance / change in t

Question 8

how to calculate distance

Answer 8

add the length of each side (no direction)

Question 9

displacement formula

Answer 9

Final x - Intial x

Question 10

slope of p vs t graph

Answer 10

velocity (m/s)

Question 11

slope of v vs t graph

Answer 11

constant velocity, acceleration (m/s/s) (m/s^2)

Question 12

y-intercept of p vs t graph

Answer 12

initial position

Question 13

y-intercept of v vs t graph

Answer 13

initial velocity

Question 14

Area of p vs t graph

Answer 14

no meaning

Question 15

Area of v vs t graph

Answer 15

displacement (change in x)

Question 16

average vs instantaneous

Answer 16

average is overall and instantaneous and is at a certain point

Question 17

P vs t math model

Answer 17

position = velocity (time) + initial position
(x = vt + x0)

Question 18

v vs t math model

Answer 18

velocity = acceleration (time) + initial velocity
(v = at + v0)
