Flashcard #3 Ch. 2 One Dimensional Motion F2024

Front

What is one-dimensional motion?

Back

One-dimensional motion refers to movement along a straight line, where only one coordinate is needed to describe the position of an object.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time

Front

How do you calculate average speed?

Back

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

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the shortest straight-line distance from the initial to the final position, including direction.

Front

What does a speed-time graph represent?

Back

A speed-time graph shows how speed changes over time, where the slope represents acceleration.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can be positive (speeding up) or negative (slowing down).

Front

What is the unit of speed in the SI system?

Back

The unit of speed in the SI system is meters per second (m/s).

Front

If a car travels 100 meters in 5 seconds, what is its speed?

Back

Speed = 100 m / 5 s = 20 m/s.

Front

What does it mean if an object is at rest?

Back

An object is at rest if its position does not change with respect to a reference point over time.

Front

What is constant velocity?

Back

Constant velocity means an object is moving at a steady speed in a straight line without changing direction.
