Motion In A Plane Flashcards
1
Q
Magnitude of A
A
(Ax²+Ay²+Az²)½
2
Q
Resultant R formula
A
R=(A² + B² + 2ABcos@)½
3
Q
Velocity-path relation
A
Direction of velocity at any point is tan to path at any point and is in the direction of motion
4
Q
r(t) formula
A
R = Ro + Vot + ½at²
5
Q
Components of velocity for projectile formula
A
Vx = Vo cosø
Vy = Vo sinø - gt
6
Q
Time of max height formula
A
Tm = Vo sinø/g
7
Q
Time of flight formula
A
Tf = 2(Vo sinø)/g
Tf = 2Tm
8
Q
Max height of projectile formula
A
Hm = (Vo sinø)²/2g
9
Q
Horizontal range formula
A
R = Vo²sin2ø/g
10
Q
Max range Rm=
A
Rm = Vo²/g
11
Q
what is time of flight?
A
total time that the projectile stays in air, from the moment it is projected to the moment it hits the ground
12
Q
what is horizontal range?
A
distance that the projectile travels in the horizontal direction
