Motion

Front

What is motion?

Back

Motion is the change in position of an object over time relative to a reference point.

Front

What is instantaneous speed?

Back

Instantaneous speed is the speed of an object at a specific moment in time.

Front

What is average speed?

Back

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

Front

What does a position vs. time graph represent?

Back

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

Front

What does a constant positive velocity look like on a graph?

Back

A constant positive velocity is represented by a straight line with a positive slope on a position vs. time graph.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object over time.

Front

What is negative acceleration?

Back

Negative acceleration, or deceleration, occurs when an object is slowing down.

Front

How can you determine acceleration from a velocity vs. time graph?

Back

Acceleration can be determined by the slope of the velocity vs. time graph.

Front

What does a curved line on a position vs. time graph indicate?

Back

A curved line indicates that the object is accelerating.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (final velocity - initial velocity) / time.
