Study Notes

Motion

  • An object is considered to be in motion if its distance from another object is changing over time.

Reference Point

  • A reference point is utilized to determine motion by comparing the position of an object with a fixed place or object.

International System of Units (SI)

  • Scientists utilize the International System of Units (SI) to quantify and describe the distance an object moves.

Meter

  • The meter is the standard unit of length in the SI system and is slightly longer than a yard.

Average Speed

  • Average speed is calculated by dividing the total distance traveled by the total time taken.

Instantaneous Speed

  • Instantaneous speed refers to the speed of an object at a specific moment in time.

Velocity

  • Velocity is defined as speed with a specified direction, combining both how fast an object is moving and where it is heading.

Slope

  • The slope of a line on a graph indicates the steepness and shows how one variable changes in relation to another.

Speed

  • Speed is the measure of how fast an object is traveling, represented as the distance covered per unit of time.
