Midterm Flashcard Part 1

Front

What is Speed?

Back

Speed is a scalar quantity that refers to how fast an object is moving, defined as the distance traveled per unit of time.

Front

What is Velocity?

Back

Velocity is a vector quantity that refers to the speed of an object in a specific direction.

Front

What is the formula for calculating Average Speed?

Back

Average Speed = Total Distance / Total 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 a Scalar Quantity?

Back

A scalar quantity is a physical quantity that has only magnitude and no direction, such as temperature or mass.

Front

What is a Vector Quantity?

Back

A vector quantity is a physical quantity that has both magnitude and direction, such as force or velocity.

Front

What is the unit of Speed in the SI system?

Back

The unit of Speed in the SI system is meters per second (m/s).

Front

Calculate the Average Speed of a car that travels 200 m in 50 seconds and then 125 m in 25 seconds.

Back

Average Speed = (200 m + 125 m) / (50 s + 25 s) = 4.33 m/s.

Front

What is the significance of direction in Velocity?

Back

Direction is crucial in Velocity as it indicates the path along which an object is moving, differentiating it from Speed.

Front

Which of the following is not a Scalar Quantity: Speed, Temperature, Volume, or Force?

Back

Force is not a Scalar Quantity; it is a Vector Quantity.
