Question 2

speed of light

Answer 2

c=3x10^-1 km/μs

Question 3

Unit for Force

Answer 3

Newton= kg*m/s^2

Question 4

Units for Velocity

Answer 4

m/s

Question 5

Units for acceleration

Answer 5

m/s^2

Question 6

Velocity

Answer 6

V=displacement/time= d/t
speed= abs(V)

Question 7

Acceleration

Answer 7

a=change in velocity/time=ΔV/t

Question 8

Uniform Accelerated Motion (UAM)

Answer 8

constant a
variables: d, V, V0, a, t
given 3, find 1, other not involved
d=displacement

Question 9

UAM Equation 2

Answer 9

V=V0 + at

missing displacement

Question 10

UAM Equation 3

Answer 10

d=V0t + (.5)at^2

missing V

Question 11

UAM Equation 5

Answer 11

V^2=(V0)^2 + 2ad

Question 12

Sin
Cos
Tan

Answer 12

Sin= opp/hyp
Cos= adj/hyp
Tan= opp/adj
