Newton's first law of motion states that an object remains at rest unless a ___force acts on it.


A.balanced
B.frictional
C.gravitational
D. net
I think it's D..?

You are right. :-)

Thank you

How does Newton’s 2nd Law of Motion relate to the mass of your racer?

The Newton’s 2ns Law is relate to racer by the mass and weight of the car.

You are close, but the correct answer is actually A. balanced force. According to Newton's first law of motion, also known as the law of inertia, an object at rest will remain at rest unless acted upon by an external or unbalanced force. A balanced force occurs when two forces acting on an object are of equal magnitude and opposite in direction, resulting in no overall change in motion. However, a net force is the overall force acting on an object and can be balanced or unbalanced. In this case, since the question asks what force is required to cause a change in motion from rest, it is specifically referring to an unbalanced force, or a force that is not counteracted by an equal and opposite force. Therefore, the correct answer is A. balanced force.
