Speed, Velocity, and Acceleration Notes Flashcard

Front

What are the SI units for velocity?

Back

Meters per second (m/s)

Front

How is velocity different from speed?

Back

Velocity is a vector quantity, which means it has both magnitude and direction, while speed is a scalar quantity, which only has magnitude.

Front

Does the speedometer in your car give your speed or velocity?

Back

The speedometer gives your speed.

Front

If you traveled 80 kilometers in 2 hours, what is your average speed?

Back

40 km/h

Front

In what situation are a car’s velocity and acceleration in opposite directions?

Back

When the car is slowing down.

Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time, regardless of direction.

Front

What is the definition of velocity?

Back

Velocity is the displacement per unit of time, including direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time.

Front

What are the SI units for acceleration?

Back

Meters per second squared (m/s²)

Front

How can you calculate average speed?

Back

Average speed can be calculated by dividing the total distance traveled by the total time taken.
