Newton’s Laws (VCE SSCE Physics): Quizzes

It remains so unless unbalanced force acts

Only its mass

Vector sum of all forces

$mg \cos \theta$

On different bodies

$N = m(a_{vertical} + g)$

Backward (opposite to velocity)

Only gravity acts on the object

They both act on the same body

Add all masses: $a = F_{net}/(m_1+m_2+...)$
