Physics Chapter 4 Motion Flashcards

Study Notes

Key Concepts in Motion

Position: Indicates an object's location relative to a defined origin, essential for understanding movement.
Origin: The reference point where the position is assigned a value of zero, serves as a baseline for measurement.
Speed: Measures how fast an object moves, calculated with the formula Speed = Distance/Time (D/T).
Average Speed: Calculated by dividing the total distance traveled by the total time taken for the entire trip, providing a general overview of motion.
Instantaneous Speed: Represents the speed of an object at a specific moment, highlighting real-time motion characteristics.
Vector: A variable that incorporates both magnitude and direction, crucial for fully understanding motion dynamics.
Velocity: Similar to speed but also includes direction; it communicates how fast and in what direction an object is moving, a vector quantity.
Axis: A component of a graph consisting of one or more number lines, used to plot values in a coordinate system.
Coordinates: Sets of values that specify a position concerning the origin, crucial for identifying locations within a given space.
Constant Speed: Describes motion where the speed remains unchanged over time, indicating uniform movement.
Slope: A graphical representation that defines the ratio of the vertical rise to the horizontal run, important for analyzing relationships between variables.
Acceleration: The rate at which velocity changes over time, a key factor in understanding how quickly an object speeds up or slows down.
Free Fall: Motion experienced by an object solely under the influence of gravity, without any other forces acting on it.
Acceleration Due to Gravity: A constant value of approximately 9.8 m/s² at Earth's surface, denoting the rate of acceleration for free-falling objects, represented as 'g'.
Projectile: An object that is propelled through space and is influenced only by gravitational forces, essential in studying motion in two dimensions.
