Study Notes
Newton's Laws of Motion
- Isaac Newton is best known for his three laws of motion
- Newton's first law states that an object at rest or in motion will remain so unless acted upon by an unbalanced force
- A force is a quantity with magnitude and direction, often represented by arrows
- The first law is also known as the law of inertia, describing an object's resistance to a change in motion
- Newton's second law states that the acceleration of an object depends on the net force and mass, represented by the equation F=ma
- The third law states that for every action, there is an equal and opposite reaction
- The International System of Units is used to describe the units for each variable in Newton's second law
- The net force is the vector sum of all the forces acting on the object
- As mass increases, the net force increases, and as acceleration increases, the net force also increases
- Newton's second law provided the foundation for scientific inquiry and greatly influenced the Enlightenment period in Europe
- Up until the 20th century, Newton's laws were regarded as the most fundamental laws of physics
- Examples of calculating net force, acceleration, and mass illustrate the application of Newton's second law
