Study Notes
Displacement-Time and Velocity-Time Graphs
- The gradient of a displacement-time graph represents velocity.
- The gradient of a velocity-time graph represents acceleration.
- The area beneath a velocity-time graph represents the total displacement of an object.
Calculating Velocity and Acceleration
- To calculate velocity from a displacement-time graph, a tangent should be drawn on the graph at a specific point to find the instantaneous gradient.
- To calculate acceleration from a velocity-time graph, the gradient of the graph at a specific point should be calculated.
Velocity as a Vector
- Velocity is a vector quantity, described by a magnitude (size) and a direction.
- For motion along a straight line, velocity can be positive (moving in one direction) or negative (moving in the opposite direction).
Graphical Analysis
- A straight line on a velocity-time graph indicates constant acceleration.
- The area beneath a velocity-time graph can be calculated to find the total displacement of an object.
- The area beneath the graph can be calculated by finding the area of a triangle (when the graph forms a triangle with the horizontal axis).
Bouncing Ball Graphs
- A displacement-time graph for a bouncing ball would show a curved shape, indicating varying velocity.
- A velocity-time graph for a bouncing ball would show a series of peaks and troughs, indicating periods of acceleration and deceleration.
