Study Notes
Types of Motion
- Distance-Time Graphs: Illustrate how distance changes over time; slope indicates speed, and the y-intercept reveals initial distance.
- Displacement-Time Graphs: Depict displacement over time; slope represents velocity, while the y-intercept shows initial displacement.
- Velocity-Time Graphs: Display velocity as a function of time; the slope reflects acceleration, and the y-intercept indicates initial velocity.
- Acceleration-Time Graphs: Represent acceleration over time; slope signifies jerk (the rate of change of acceleration), and the y-intercept denotes initial acceleration.
Key Features
- Gradient (Slope): Indicates the relationship between distance, velocity, or acceleration based on the graph type.
- Intercepts: Provide initial values relevant to distance, displacement, velocity, or acceleration.
- Shape: A straight line signifies uniform motion, while a curve suggests non-uniform motion.
- Area Under the Curve: Represents the total distance traveled or displacement depending on the graph.
Analyzing Graphs
- Identify Motion Type: Determine whether the graph pertains to distance, displacement, velocity, or acceleration.
- Slope Determination: Calculate the slope and interpret its significance regarding speed, velocity, or acceleration.
- Identify Intercepts: Recognize intercepts and understand what they signify in terms of initial conditions.
- Shape Analysis: Examine the graph's shape to infer the nature of the motion (uniform vs. non-uniform).
- Calculate Area Under Curve: If relevant, find the area under the graph to ascertain total distance or displacement.
