Speed and Velocity Notes Flashcardizz P

Front

What is speed?

Back

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

Front

What is velocity?

Back

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

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (only magnitude), while velocity is a vector quantity (magnitude and direction).

Front

What is the formula for calculating average speed?

Back

Average speed = total distance / total time.

Front

What is a scalar quantity?

Back

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

Front

What is a vector quantity?

Back

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

Front

If a car travels 100 miles in 2 hours, what is its average speed?

Back

Average speed = total distance / total time = 100 miles / 2 hours = 50 mph.

Front

What does it mean if an object has a constant speed?

Back

It means the object is moving at the same speed throughout its motion, without speeding up or slowing down.

Front

What is instantaneous speed?

Back

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

Front

How does direction affect velocity?

Back

Since velocity includes direction, changing the direction of an object's motion changes its velocity, even if its speed remains the same.
