Study Notes
Newton's Laws of Motion
- Newton's first law of motion describes the Law of Inertia, stating that an object at rest will stay at rest unless acted upon by an unbalanced force.
- Inertia refers to the tendency of an object to maintain its state of motion, whether at rest or moving in a straight line.
- An object's mass determines its inertia, with greater mass resulting in greater resistance to changes in motion.
- Velocity is defined as moving at a consistent speed and direction unless an unbalanced force alters that trajectory.
Newton's Second Law of Motion
- Known as the Law of Acceleration, it asserts that an unbalanced force applied to a mass results in an acceleration of that mass.
- The relationship between force, mass, and acceleration is encapsulated in the equation F = ma, where F represents force, m is mass, and a is acceleration.
- Increasing the applied force results in greater acceleration, while decreasing the applied force leads to lesser acceleration.
- When the same force is applied to different masses, a larger mass results in smaller acceleration, while a smaller mass yields larger acceleration.
Newton's Third Law of Motion
- Known as the Law of Action-Reaction, it dictates that for every action force, there is an equal reaction force acting in the opposite direction.
- An action force generates an equal reaction force that occurs simultaneously, ensuring that forces are always paired.
- Forces must always occur in pairs, highlighting the interconnected nature of actions within physical interactions.
