Newton's Laws of Motion

These flashcards cover key concepts from Newton's Laws of Motion, focusing on relationships between force, mass, and acceleration, along with essential laws and definitions.

What is the relationship between force and acceleration as described by Newton’s Second Law?

Acceleration is directly proportional to the force applied.

According to Newton’s Second Law, what is the relationship between mass and acceleration?

Acceleration is inversely proportional to the mass when the force is constant.

What is the statement of Newton's Second Law?

The sum of all external forces acting on an object is equal to the product of the object's mass and its acceleration: F = ma.

What is inertia?

Inertia is the tendency of an object to resist changes in its state of motion.

What occurs when an object is acted upon by an unbalanced force?

The object accelerates.

What is Newton's First Law commonly referred to as?

The Law of Inertia.

Where does the reaction force occur according to Newton’s Third Law?

The reaction force occurs between two bodies, where they exert forces on each other in opposite directions.

What does static equilibrium mean?

A system is in static equilibrium when it is not accelerating and the net force is zero.

What is the purpose of a free body diagram in dynamics problems?

To visually represent all forces acting on an object and resolve them into components.

What is the coefficient of friction and how does it relate to normal force?

The coefficient of friction (μ) relates the frictional force to the normal force (f = μN).

What happens to the frictional force when a block begins to accelerate?

The friction becomes kinetic and is described by the kinetic coefficient of friction (fk = μkN).
