Motion and Graphing Motions

Front

What is the definition of velocity?

Back

Velocity is the rate of change of displacement of an object, including both speed and direction.

Front

What does a velocity-time graph represent?

Back

A velocity-time graph represents how the velocity of an object changes over time.

Front

What is the formula for calculating acceleration?

Back

Acceleration is calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What does a horizontal line on a velocity-time graph indicate?

Back

A horizontal line on a velocity-time graph indicates that the object is moving at a constant velocity.

Front

What does a positive slope on a velocity-time graph indicate?

Back

A positive slope on a velocity-time graph indicates that the object is accelerating.

Front

What does a negative slope on a velocity-time graph indicate?

Back

A negative slope on a velocity-time graph indicates that the object is decelerating or experiencing negative acceleration.

Front

What is the SI unit for velocity?

Back

The SI unit for velocity is meters per second (m/s).

Front

What is the significance of the area under a velocity-time graph?

Back

The area under a velocity-time graph represents the displacement of the object over the time interval.

Front

What is the relationship between acceleration and direction?

Back

Acceleration can occur in the same direction as the velocity (speeding up) or in the opposite direction (slowing down).
