1. density equation
density = mass/volume

• p=m/v
2. average speed
average speed= distance/time

• _
• v =d/t
3. acceleration equation
acceleration=change of velocity/time

=final velocity-initial velocity/time

a=v_final-v_initial/t
4. average velocity
average velocity=final velocity+initial velocity/2

• _
• v = final v + initial v /2
5. distance equation
distance=1/2(acceleration)(time)^2
6. force equation
force=mass x acceleration

f=ma
7. weight equation
• weight=mass x acceleration due to gravity
• w=m(g)
8. momentum equation
momentum=mass x velocity

p=mv
9. change of momentum
change of momentum=force x time
10. centripetal acceleration equation
11. centripedal force equation
centripetal force=(mass x velocity squared)/radius of circle

f=mv^2/r
12. gravitational force equation
gravitational force=constant x (onemass x another mass)/distance squared

f=g (m1m2)/d^2
13. work equation
work=force x distance

w=fd
14. power equation
power=work/time
