Which of Newton's Three Laws Applies? Law 1, 2, or 3?

Pushing a cart down the hall, when you try to turn it it tries

to go straight.

More acceleration takes more force.

When you push your knuckles into a table, it hurts your knuckles.

A ball thrown into the ground bounces back up.

1. Newton's first law

2. Newton's second law

3. Newton's third law

Explanation:

1. Newton's first law stated, In an inertial frame of reference, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a force ... this is base of the concept of inertia.

2. Newton's second law stated, In an inertial frame of reference, the vector sum of the forces F on an object is equal to the mass m of that object multiplied by the acceleration a of the object: F = ma, or in easier words, F is directly proportional to a.

3. Newton's third law stated, When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body., In this case, the Normal Are opposite with gravititional force.
