Flashcards in 2D Motion Deck (15):

1

## What is the equation for trajectory?

###
y=-1/2g(x/v)^2 or

y=-1/2gt^2 and x=vt

2

## Are the x- and y-components dependent on each other?

### No, they both act independently in their own vectors

3

## For projectile motion, is horizontal velocity linear, quadratic or constant?

###
Constant

x=vt

4

## For a projectile motion, is the vertical velocity linear, quadratic, or constant?

###
Quadratic

y=-1/2gt^2

5

## What is Relative Velocity?

### Resultant of two vectors of velocity

6

## When a ball is projected, will its velocity ever reach zero?

### Yes, at its highest point

7

## What will a projectile motion look like on a v vs t graph?

### Straight line going down in the negative direction (ie. y=-x)

8

## For projectile motion, where is the highest point plotted on a v vs t graph?

### Where the graph intersects the x-axis; y=0

9

## For projectile motion, where is the upward motion on a v vs t graph? (+/-)

### When y is greater than 0; before the graph intersects the x-axis

10

## For projectile motion, where is the downward motion on a v vs t graph? (+/-)

### When y is less than 0; after the graph intersects the x-axis

11

## At what angle will maximum range be reached?

### 45 degrees

12

## What is Frequency?

### Number of revolutions per second

13

## What is Centripetal Acceleration?

### Acceleration toward the center

14

## What is the equation for frequency?

### f=1/T
