Study Notes
Linear Motion
- Linear motion with variable velocity is called accelerated motion.
- The mathematical description of the position of a particle in linear motion is given by the position-time graph.
- According to Newton's first law of motion, objects that do not experience any net force will maintain their state of motion, i.e., remain in motion or at rest.
- External forces like friction and gravity can cause an object to change the direction of its motion under everyday circumstances.
- Another name for linear motion is rectilinear motion.
- Linear motion is the most basic type of motion and is characterized by a one-dimensional nature along a straight line.
Key Concepts
- Acceleration is a characteristic of linear motion with variable velocity.
- Net force plays a crucial role in determining the motion of an object, as stated in Newton's first law of motion.
- Position-time graph is a mathematical tool used to describe the position of a particle in linear motion.
