Chapter 9- Computing the next move

Question 1

Suvat equations

Answer 1

v=u+at
S=0.5(u+v)t
S=ut+0.5at^2
S=vt-0.5at^2
v^2=u^2+2as

Question 2

Relative velocity of B relative to A=

Answer 2

take Va from every object

Vba=Vb-Va

Question 3

work done=

Answer 3

force x distance moved parellel to force

Question 4

kinetic energy=

Answer 4

1/2mv^2

Question 5

elastic potential energy=

Answer 5

1/2kx^2

Question 6

gpe=

Answer 6

mgh

Question 7

power=

Answer 7

energy/time
or work/time
or force x velocity (in direction of force)
