Equations(density, percent error, Energy)

Question 1

Density

Answer 1

d= mass(kg)/Volume (L)

Question 2

Percent Error

Answer 2

Percent Error=average(five points)-True Value / True Value

Question 3

Gravity

Answer 3

9.8

Question 4

Equation for energy?

Answer 4

Kinetic energy plus potential energy equals energy

Ek + Ep = E

Question 5

What is the equation for Kinetic Energy?

Answer 5

Ek = 1/2•m•v^2

V-velocity
M-mass

Question 6

Joule

Answer 6

Kg•m/s^2

Kg•m^2•s^-2

NEVER FORGET TO SQUARE

Question 7

What is the equation for potential energy?

Answer 7

Ep=mph= kg•m/s^2•m

Mass(Kg)
Gravity(9.8m/s^2)
Height (m)
