Forces and motion formula

Formula for distance

• D = S x T

• D = S/T

• D = T/S

• D = F x S

Formula for acceleration

• a= change in time/change in velocity

• a= v-u/t

• a= speed x velocity

• a= time x velocity

Formula for resultant force

Newton's second law

• F= a x t

• F = a x s

• F= m x a

• W = m x g

Formula for weight

• F= m x a

• W= m x g

• W= m x a

• F= m x g

Momentum

• p = m x a

• p = m x v

• m = m x v

• m = m x a

Impact force

*Clue same as resultant force just expanded

• F = m x w

• F = mv-mu/t

• F = m x s

• F = ma-mv/t

Impulse

• F= m x a

• I = m1-m2

• I = a x s

• F x t = mv-mu

Conservation of momentum

• m1u1+m2u2=

  m1v1 +m2v2

• m2u2+m1u2=

  m1v3+m2v4

• clockwise = anticlockwise

• moving in circles

Moment

• clockwise = clockwise

• clockwise + anticlockwise = 5

• clockwise = anticlockwise

• anticlockwise = the same way

newtons first law

• stationary = stationary

• moving = moving at constant velocity

• stationary = continue moving

• F= m x a
