Study Notes
Creating Graphs
- Steps to create a graph:
- Identify dependent (y-axis) and independent variables (x-axis).
- Create a scale for axes based on the largest value.
- Plot data points by aligning x-values with corresponding y-values.
- Draw a smooth curve to represent the data trend without connecting individual points.
Variables
- Distance is always a positive value.
- Position can be either positive or negative, depending on its relation to the origin.
Number Direction
- Positive numbers extend right (in front of the origin) and negative numbers extend left (behind the origin).
Vector Variables
- Variables such as position, speed, and force can be both positive and negative; these are known as vectors.
Axes Orientation
- Position is plotted on the vertical axis (y-axis) and time on the horizontal axis (x-axis).
Physical Science
- Focuses on the relationships between various variables.
Weak Relationships in Graphs
- A weak relationship between variables results in a graph that appears as scattered dots without a clear pattern or curve.
Models in Science
- A model connects two or more variables to demonstrate relationships.
Line Steepness
- A steeper line on a graph indicates faster movement.
Acceleration Calculation
- Calculated by dividing the change in speed by the total time taken.
Deceleration
- The term used to describe an object's slowing down.
Speed vs. Acceleration
- Constant speed remains unchanged, while constant acceleration involves a consistent change in speed over time.
Acceleration Occurrence
- Acceleration happens with any change in speed, direction, or both simultaneously.
Curved Motion
- Caused by sideways acceleration, resulting in a curved path of motion.
Parabola
- Defined as a bowl-shaped curve.
Axis Identification
- Independent variable is placed on the x-axis, dependent variable on the y-axis.
Acceleration Metrics
- Measured in meters per second squared (m/s²).
Velocity
- Speed that includes direction is referred to as velocity.
Graphing Acceleration
- Represented by the slope of the line on a graph.
Coordinate System
- In a coordinate pair (3,5), 3 corresponds to the x-value and 5 corresponds to the y-value.
Acceleration definition
- The rate at which velocity changes.
Gravity and Curved Paths
- The force acting on an object moving on a curved path due to gravity is often referred to as a parabola.
Average Speed Calculation
- Average speed can be calculated by dividing the change in speed by the change in time.
Slope Formula
- The slope of a line is determined by the formula: slope = rise / run.
Projectile Motion
- Describes objects moving through space, influenced only by gravity.
