Study Notes
Motion and Reference Points
- A reference point is essential for determining an object's motion, providing a basis for comparison.
- Motion involves a change in position relative to a reference point.
Speed and Velocity
- Constant speed refers to a situation where an object's speed remains unchanged over time.
-
Speed is defined as the distance an object travels within a specific unit of time, calculated using the formula:
- Speed = Distance / Time
- Average speed is found by dividing total distance by total time taken.
Distance and Acceleration
- The formula for distance is expressed as:
- Distance = Speed x Time
- Distance, in kinematics, is usually represented on the y-axis of a graph.
- Acceleration measures how quickly an object's velocity changes, which can involve increases or decreases in speed, or changes in direction. It is calculated by dividing the change in speed by the time period over which the change occurs.
Velocity
- Velocity encompasses both the speed of an object and its direction of travel, providing a more complete picture of its motion.
Theory of Plate Tectonics
- The Theory of Plate Tectonics studies the movement of the Earth's plates, which can be measured in millimeters per year, indicating the dynamic nature of the planet's crust.
