Answer 1

The rate of change of displacement

W=@/T

Question 2

Revolutions equation

Answer 2

@=s/r

Question 3

Velocity equation

Answer 3

V=wr

Question 4

Acceleration equations

Answer 4

A=v^2/r
A=rw^2

Question 5

Centripetal

Answer 5

“Central seeking”

Question 6

Angular velocity equation

Answer 6

W=@/t

Question 7

F=ma centripetal equation

Answer 7

F=mrw^2

Question 8

Newtons 1st law

Answer 8

A body will remain at rest or constant velocity unless acted upon by a resultant force

Question 9

Newtons 2nd law

Answer 9

A body will experience an acceleration,a, when acted upon by a force,f, given that mass,m, is constant

Question 10

Newtons 3rd law

Answer 10

If body A exerts a force on body B, body b will exert an equal and opposite force on body A.

Question 11

Fr centripetal acceleration equation 2

Answer 11

Fr=mv^2/r

Question 12

Tension of pendulum at different points of the cycle equations (3)

Answer 12

12 o’clock: T=mv^2/r -W
3/9 o’clock: T=mv^2/r
6 o’clock: T=mv^2/r +W
