what does the hypotenuse represent?
How would you calculate it?
the hypotenuse represents magnitude
it can be calculated by using a²+b²=c²
what does Theta represent?
How would you calculate it?
Theta represent the direction
it can be calculated using tan- (y/x)
How would you calculate x?
x=rcos0
x=11cos26
x=10 (about 9.8)
How would you calculate y?
y=rsin0
y=11sin26
y=4.8 (about 4.8)
In a free fall equation Vi is what, unless stated otherwise?
Vi=0
In a free rise equation Vf is what, unless stated otherwise?
Vf=0
Lower velocity causes a…
shallow slope
greater velocity causes a…
steeper slope
Negative velocity
Negative slope (line moves downward)
How do you calculate acceleration?
Change in velocity/change in time
vf-vi/tf-ti
How do you calculate velocity?
displacement (m)/ time (s)
v=d/t
Vector quantity
Magnitude and direction
scalar quantity
magnitude only
