Flashcards in 1D Motion Deck (20):
1

Is distance a Scalar or Vector quantity?

Scalar (only magnitude)

2

Is displacement a Scalar or Vector quantity?

Vector (both magnitude and direction)

3

What is Kinematics?

Study of HOW something moves; involves change in position over time; can be uniform or uniform

4

What is the equation for Average Velocity?

v=Δx/Δt (units= m/s)
v= (v+vo)/2

5

What is the equation for Instantaneous Velocity?

x=vΔt
v=x/Δt

6

What is the equation for Relative Velocity?

Same direction: v=v1-v2
Opposite direction: v=v1+v2

7

What does the slope of a displacement vs time graph represent?

v=Δx/Δt
slope= velocity

8

What does the area of a displacement vs time graph represent?

Nothing lolz

9

What does the slope of a velocity vs time graph represent?

a=Δv/Δt
slope= acceleration

10

What does the area of a velocity vs time graph represent?

x=vΔt
area= displacement

11

What is Acceleration?

A rate of change in velocity; vector quantity

12

What is the equation for Average Acceleration?

Δv=at

13

What does it mean to have zero acceleration?

ΣF=0; does not necessarily mean at rest, could have constant velocity

14

What is the equation for displacement in the x-direction?

x=vt
v^2=vo^2+2a(Δx)

15

What does it mean to have negative velocity?

To have a backward motion or going back to the origin

16

What does it mean to have a negative acceleration?

To slow down

17

What is the value of Gravity?

-9.8 m/s^2
symbol: g

18

What is the equation for displacement in the y-direction?

y=-1/2gt^2

19

What is the equation for displacement in the y-direction with an initial velocity?

down: y=-vot-1/2gt^2
up: y=vot-1/2gt^2

How to find the instantaneous velocity of an acceleration object on a x vs t graph?

Since the graph is curved, draw a tangent line and find its slope
