Newton’s Law of Motion is:

The rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction, in which the force acts
All listed here
To every action, there is always an equal and opposite reaction
Everybody continues in its state of rest or of uniform motion in a straight line, unless it is acted upon by some external force

‘ω’ rad/sec is the angular velocity of a crank whose radius is ‘r’. If it makes θ° with inner dead centre and obliquity of the connecting rod ‘l’ is ‘ϕ’, the velocity v of the piston, is given by the equation

ω (l sin ϕ + r cos ϕ tan θ)
ω² (l cos ϕ + r sin ϕ tan θ)
ω² (l sin ϕ - r cos θ tan ϕ)
ω² (l sin ϕ + r cos φ tan θ)
