Question

an object that is at rest will remain at rest. the acceleration of an object is equal to the sum of the forces acting on the object divided by the mass of the object. $a=\frac{f_{net}}{m}$ inertia. the horizontal acceleration of a skater after being pushed by someone. an object that is moving will continue to move in a straight line with constant speed, if and only if the net force acting on that object is zero. are these an example of newtons 1st law, or his 2nd law? <<timer>>

Explanation:

Newton's first law states an object at rest stays at rest and an object in motion stays in motion with a constant velocity unless acted upon by an external force. Newton's second law is $a=\frac{F_{net}}{m}$, where acceleration is the net - force divided by mass. The statements "An object that is at rest will remain at rest" and "An object that is moving will continue to move in a straight line with constant speed, if and only if the net force acting on that object is zero" are examples of Newton's first law. The statement "The acceleration of an object is equal to the sum of the forces acting on the object divided by the mass of the object" is an example of Newton's second law. Inertia is related to Newton's first law. The horizontal acceleration of a skater after being pushed is related to Newton's second law.

Answer:

The statements "An object that is at rest will remain at rest" and "An object that is moving will continue to move in a straight line with constant speed, if and only if the net force acting on that object is zero" are examples of Newton's 1st Law. The statement "The acceleration of an object is equal to the sum of the forces acting on the object divided by the mass of the object" is an example of Newton's 2nd Law. Inertia is related to the 1st Law and the horizontal acceleration of a skater after being pushed is related to the 2nd Law.
