Explain the equation for force.
Force:
According to Newton's second law of motion, force is equal to the change in momentum of the body.
m is the acceleration.
a is the acceleration.
is the change in velocity.
Derivation of force equation from the momentum (p): considering mass is constant and velocity is changing.
Derivation of force equation from the momentum: considering velocity is constant and mass is changing.
Derivation of force equation from the momentum: considering both mass and velocity changes.
