Circular Path
If Vx is 2 and Vy is 2 at the beginning of a projectile, what is Vx when the projectile lands.
2
The path a projectile takes in the y direction or vertical axis
Range
What other angle produces the same trajectory as 30 degrees?
60

Centripetal force
Two cars go around a curve. If one is moving twice as fast, which car would be more likely to go off the road?
The faster one
What is the formula for distance in circular motion?
d=2(pi)rn
What angle would a projectile be for maximum trajectory?
45

trick question. x never chnages
How does tension relate to circular motion
whatever i say is correct
An ice skater is spinning in a circle with her arms out. What would you expect to happen to her speed if she brought her arms in. Why is this the case?
She speeds up because her radius is smaller
How are revolutions represented in math formulas?
n
What is the formula for Velocity in the y direction of a projectile?
v=gt
The horizontal motion of a projectile can be explained by the law of...
inertia
Acceleration pointing to the center of the path
Centripetal acceleration
You are spinning a ball on a string around you when the string suddenly snaps. In what direction would the ball go?
In the direction it was going
You have a ball on a string and it has a mass of 4kg. if it spins for 6 revolutions in 6 seconds with a radius of 0.5 what is the total distance?
2x3.14x0.5x6 = 18.84
