• A force is a push or pulll

Which of the following is Newton's 2nd law?

• For every action, there is an equal and opposite reaction.

• The acceleration of an object is produced by a net force and is inversely proportional to the mass of the object.

• An object will remain at rest or in motion unless an outside force acts upon it.

• A force is a push or pulll

Which of the following is Newton's 3rd law?

• For every action, there is an equal and opposite reaction.

• The acceleration of an object is produced by a net force and is inversely proportional to the mass of the object.

• An object will remain at rest or in motion unless an outside force acts upon it.
