Physics 1

Question 1

center of buoyancy

Answer 1

located at center of mass of fluid displaced by submerged object

Question 2

range

Answer 2

range = (Vx) (t)

Question 3

distance/height

Answer 3

distance/height = (rate) (time)

X = (1/2) (a) (t)^2

Question 4

velocity

Answer 4

(or 2ax)

Question 5

time in air

Answer 5

tair = (2V) / (g)

round trip times, V must be Vy initial

Question 6

terminal velocity

Answer 6

mg = Fair

Question 7

force of gravity

Answer 7

G = 6.67x10^11

can be used everywhere

F = mg

can be used close to earth

Question 8

gravitational field

Answer 8

Question 9

gravitational potential energy

Answer 9

can be used in space, or when g ≠ 10 m/s^2

PE = mgh

can be used near earth

Question 10

friction

Answer 10

Question 11

inclined planes

Answer 11

Question 12

Hooke’s Law

Answer 12

F = k∆x

*** pay attention to sign - or +

f = 1/2π √(k/m)

f = frequency = 1/T (period)

Question 13

elastic potential energy

Answer 13

Question 14

simple harmonic motion

Answer 14

T = time of period = full cycle (back and forth)

Question 15

density

Answer 15

Question 16

buoyant force

Answer 16

Question 17

apparent weight

Answer 17

Question 18

pressure

Answer 18

Question 19

fluid pressure

Answer 19

h = depth

p = density

Question 20

flow rate

Answer 20

Question 21

cardiac output

Answer 21

Question 22

Bernoulli’s Equation

Answer 22
