16

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.

25

Torque

Radius x force x sin®
Counterclockwise is the positive direction and clockwise is the negative direction
