Speed, Velocity, and Acceleration Flashcard

Front

What is speed?

Back

Speed is the distance traveled per unit of time, without considering direction.

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 at which an object changes its velocity.

Front

If a car drives 50 miles north, what is its velocity?

Back

50 miles per hour north.

Front

How do you calculate velocity?

Back

Velocity = Distance / Time, including direction.

Front

A boat travels 80 kilometers east in 4 hours. What is its velocity?

Back

20 kilometers per hour east.

Front

What happens to velocity if an object changes direction?

Back

The velocity changes because velocity includes direction.

Front

If a hiker walks 24 kilometers east in 6 hours, what is their velocity?

Back

4 kilometers per hour east.

Front

What is the difference between speed and velocity?

Back

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

Front

What is an example of acceleration?

Back

A car speeding up from 30 miles per hour to 60 miles per hour.
