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.
