Study Notes
Motion in One Dimension
- Speed and velocity are often confused, but speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that refers to an object's speed in a specific direction.
Displacement
- Displacement is the distance an object travels from its initial to its final position, and it can be positive, negative, or zero.
Instantaneous Velocity
- Instantaneous velocity is represented by the equation dv/dt = Δv / Δt, where dv is the change in velocity and dt is the change in time.
Recommended Resources
- For learning about motion in one dimension, the recommended reading is "Motion in One Dimension" by OpenStax College Physics.
- For learning about motion along a straight line, the recommended video is "Motion Along a Straight Line" by 3Blue1Brown.
Derived Physical Quantities
- Velocity is a derived physical quantity, meaning it can be calculated from other physical quantities like displacement and time.
Velocity Calculation
- Velocity can be calculated using the equation v = Δx / Δt, where v is velocity, Δx is the change in position, and Δt is the change in time.
