Physics Motion Flashcard 07

Front

What is motion in physics?

Back

Motion is the change in position of an object over time.

Front

What is a Position vs. Time graph?

Back

A Position vs. Time graph shows how the position of an object changes over time.

Front

What does a horizontal line on a Position vs. Time graph indicate?

Back

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

Front

What does a steep slope on a Position vs. Time graph represent?

Back

A steep slope indicates a high speed of the object.

Front

What is speed?

Back

Speed is the distance traveled per unit of time.

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What does a downward slope on a Position vs. Time graph indicate?

Back

A downward slope indicates that the object is moving back towards the starting point.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

What does a positive acceleration mean?

Back

Positive acceleration means that the object is speeding up.
