Pregunta 4
Pregunta
What is newtons third law?
Respuesta
-
For every action there is an equal and opposite reaction
-
Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
-
The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.
