# VCE Physics/Unit 2/AoS 1/Dynamics (how forces affect motion)

< VCE Physics‎ | Unit 2‎ | AoS 1
• apply Newton’s three laws of motion to a body on which forces act: ${\displaystyle a={\frac {F_{net}}{m}}}$, ${\displaystyle F_{\text{on A by B}}=-F_{\text{on B by A}}}$
• explain changes in momentum as being caused by a net force: ${\displaystyle F_{net}={\frac {\Delta p}{\Delta t}}}$
