newtons second law of motion

1. what is the acceleration of an object dependent upon?
2. define mass.
3. list newtons second law and the equation associated with the law.
4. example:

Explanation:

1. Galileo Galilei's work on motion was a significant foundation for Newton's studies. He made important discoveries about falling - bodies and motion on inclined planes.
2. Inertia is the tendency of an object to resist changes in its state of motion. An object at rest tends to stay at rest, and an object in motion tends to stay in motion with a constant velocity unless acted upon by an external force.
3. Newton's first law of motion states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
4. Example: A book placed on a table remains at rest because there is no unbalanced force acting on it. When a bus suddenly starts moving, passengers tend to fall backward due to their inertia (they were initially at rest).

For Newton's Second Law of Motion:

1. The acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
2. Mass is a measure of the amount of matter in an object. It is a scalar quantity and is constant regardless of the object's location.
3. Newton's second law states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. The equation is $F = ma$, where $F$ is the net force, $m$ is the mass, and $a$ is the acceleration.
4. Example: Pushing a lighter box (less mass) with the same force as a heavier box (more mass) will result in the lighter box having a greater acceleration.

Answer:

1. Galileo Galilei
2. The tendency of an object to resist changes in its state of motion.
3. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
4. A book on a table remains at rest until a force acts on it.

For Newton's Second Law of Motion:

1. Net force and mass.
2. A measure of the amount of matter in an object.
3. The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. Equation: $F = ma$.
4. Pushing a lighter box with the same force as a heavier box gives the lighter box greater acceleration.
