Speed, Velocity, and Acceleration

Front

What is speed?

Back

Speed is the distance traveled per unit of time. It is a scalar quantity, meaning it only has magnitude and no direction.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction. It is a vector quantity, meaning it has both magnitude and direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time. It can be positive (speeding up) or negative (slowing down).

Front

What does a flat line on a distance vs. time graph indicate?

Back

A flat line indicates that the object is not moving; it is stationary.

Front

What does a straight diagonal line on a distance vs. time graph represent?

Back

A straight diagonal line represents constant speed; the object is moving at a steady pace.

Front

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

Back

A curved line indicates changing speed; the object is accelerating or decelerating.

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 is deceleration?

Back

Deceleration is a decrease in speed or negative acceleration; it occurs when an object slows down.

Front

What does a steeper slope on a distance vs. time graph indicate?

Back

A steeper slope indicates a higher speed; the object is covering more distance in less time.
