Speed, Velocity Acceleration, Graphs

Front

What is speed?

Back

Speed is the distance traveled per unit of time, calculated as distance/time.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time

Front

What does a constant speed mean?

Back

A constant speed means that an object is moving at the same rate over time.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of a moving object.

Front

Which of the following is an example of acceleration?

Back

A bat hitting a ball (because it changes the speed of the ball).

Front

What does a speed vs. time graph show?

Back

A speed vs. time graph shows how speed changes over time.

Front

What does a horizontal line on a speed graph indicate?

Back

A horizontal line indicates constant speed.

Front

What does a slope on a speed graph represent?

Back

The slope represents acceleration; a steeper slope indicates greater acceleration.

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).
