Study Notes
Motion in One Dimension
-
Definition of Distance and Displacement:
- Location needs a frame of reference (e.g., coordinates)
- Distance is the total path traveled, independent of direction
- Displacement is the difference between final and initial positions (a vector)
-
Displacement and Distance Example:
- Travel from Montreal to Toronto (500 km) and back to Montreal results in a distance of 1000 km and a displacement of 0 km.
-
Speed and Velocity:
- Speed is a scalar, indicating the rate of distance traveled (average speed considers total time).
- Velocity is a vector, measuring the rate of displacement (average velocity is total displacement over total time).
-
Instantaneous Velocity:
- The instantaneous velocity is the limit of the average velocity as time approaches zero
-
Acceleration:
- Acceleration is the change in velocity over time
- Constant acceleration is a common assumption in introductory physics problems
-
Acceleration Problems:
- Speed and velocity are functions of time.
- In many situations, acceleration is constant over time
- Acceleration requires a force (contact or non-contact).
- Constant acceleration can be described graphically or using equations.
Kinematic Equations
-
Equations for Constant Acceleration:
- Equations link displacement, initial and final velocity, acceleration, and time.
- The formulas are beneficial for understanding motion with constant acceleration.
-
Relationship Between Velocity and Acceleration:
- With constant acceleration, velocity changes linearly over time.
- The slope of a velocity-time graph represents acceleration
-
Determining Displacement from Velocity:
- The area under a velocity-time graph gives the displacement over a given time period (this is also true with constant acceleration).
-
Solving Problems with Given Quantities:
- Several equations can be used to solve 1-dimensional motion problems with known values.
- Selecting the right formula is crucial for solving problems.
Application of Kinematic Equations
- Example Problem (Throwing a Stone):
- Example involving initial velocity, height, and maximum height reached to determine time, and velocity at different points.
- Shows how to apply 1-dimensional motion equations.
