12. Motion in 1D

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the direction.

Front

What is distance?

Back

Distance is the total length of the path traveled by an object, regardless of direction.

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

What is average velocity?

Back

Average velocity is the total displacement divided by the total time taken.

Front

What does a negative acceleration indicate?

Back

A negative acceleration indicates that an object is slowing down.

Front

What is the formula for calculating average speed?

Back

Average Speed = Total Distance / Total Time.

Front

What does a position-time graph represent?

Back

A position-time graph shows how the position of an object changes over time.

Front

What is the significance of the slope in a position-time graph?

Back

The slope of a position-time graph represents the velocity of the object.

Front

What does a flat line on a position-time graph indicate?

Back

A flat line indicates that the object is at rest and not changing its position.

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately -9.8 m/s².
