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

15

What is the equation for centripetal acceleration?

a=v^2/r
a=4π^2r/T^2
