Newton's second law
F = m x a
acceleration is inversely proportional to mass of the object. Force and acceleration are directly proportional.

Newton's third law
When two objects interact, the forces they exert on each other are equal and opposite
e.g Cat sitting on the ground : contact gravitational forces between Earth and cat - cat pulls Earth up - Earth pulls cat down
Rocket taking off - force of gases being ejected from rocket is equal to force that lifts the rocket from the surface
