## Overall velocity

### Initial velocity v(o) + acceleration (time)

17

## Acceleration d1t gravity

### 9.8 m/s

18

## Force

### Mass x acceleration; measured in Newtons (N)

19

## Weight

### Mass x acceleration d/t gravity; also measured in Newtons (N)

20

## Normal force

### The force perpendicular to the surface

21

## Friction force

### The force parallel to the surface

22

## Distance

### (Acceleration x time^2)/2

23

## Gravitational force

###
(G x mass1 x mass2) / r^2

where G is the gravitational constant (6.67x10^-11 Nm^2/kg^2) and r is the distance between their centers

24

## Translational equilibrium

### The sum of forces pushing the object through space is counterbalanced by the sum of forces acting in the opposite direction.
