what must be happening, according to newton's second law of motion, if a rigid body of unchanging mass is observed accelerating? responses a force was once applied but is now not being applied. a force was once applied but is now not being applied. the mass must be changing. the mass must be changing. no force was or is being applied to the mass. no force was or is being applied to the mass. a force is being applied to the mass. a force is being applied to the mass.

Respuesta :

If a rigid body of constant mass is observed accelerating, what must be happening? A force is being applied to the mass.

What is the cause of this acceleration in terms of Newton's second rule of motion?

Newton's second law states that when a constant force is given to a big body, it will accelerate or change its velocity at a constant rate. In the simplest case, if a force is applied to an object at rest, the object will accelerate in that direction.

What practical implications does Newton's second law of motion have for us?

Newton's second law states that a force can alter a body's motion. A body's momentum changes in size and direction at the same rate as the force pushing on it.
