What characteristic defines uniform straight-line motion?
What characteristic defines uniform straight-line motion?
- The speed remains unchanged throughout the motion. (correct)
- The distance covered is never the same over equal time intervals.
- The motion typically involves acceleration.
- The speed varies at different times.
How is speed calculated based on the given information?

Flashcards
Speed
Speed
The rate at which an object changes its position over time. It is calculated by dividing the distance traveled by the time taken.
Uniform Straight-Line Motion
Uniform Straight-Line Motion
Motion in a straight line where the object travels at a constant speed without changing direction.
