What is the definition of a kinematic system?
✔✔A kinematic system describes the motion of points, bodies, or systems of bodies without
considering the forces that cause this motion.
How is work defined in the context of physics?
✔✔Work is defined as the product of force applied to an object and the distance over which that
force is applied in the direction of the force.
What does the term "moment of inertia" refer to?
✔✔Moment of inertia refers to a measure of an object's resistance to changes in its rotation,
depending on the mass distribution relative to the axis of rotation.
How does Newton's second law of motion relate to acceleration?
✔✔Newton's second law states that the acceleration of an object is directly proportional to the
net force acting upon it and inversely proportional to its mass.

, What is the principle of conservation of momentum?
✔✔The principle of conservation of momentum states that the total momentum of a closed
system remains constant if no external forces act on it.
What role does the center of mass play in mechanics?
✔✔The center of mass is the point at which the mass of a body or system is concentrated,
influencing how the object moves and balances under various forces.
How do pulleys reduce the effort needed to lift a load?
✔✔Pulleys change the direction of the force applied and can reduce the amount of force needed
to lift an object by distributing the load across multiple ropes.
What is the significance of the Bernoulli principle in fluid dynamics?
✔✔The Bernoulli principle states that an increase in the speed of a fluid occurs simultaneously
with a decrease in pressure or potential energy, which is crucial in understanding airflow and lift
in aviation.
What is the difference between static and dynamic equilibrium?
