**Force, Mass, Acceleration, Weight, Gravity **

**RE****M****EMBER: ** A weight is a special case of force.

example 1: what is the mass of a 200. kg object?

200. kg

example 2: what is the weight of a 200. kg object?

weight = mass x gravity

200. kg x 9.8 m/s2 =

1960 kg m/s2 =

1960 newtons

example 3: what is the mass of a 200. newton object?

mass = weight / gravity

200. kg m /s2 / 9.8 m/s2 =

20.4 kg

example 4: A little boy pushes a wagon with his dog in it. The mass of the dog and wagon together is 45 kg. The wagon accelerates at 0.85 m/s2. What force is the boy pulling with?

m = 45 kg

a = 0.85 m/s^2

F = ?

F = ma

F = (45 kg)(0.85 m/s^2)

__F = 38.25 N__
