2024 Semester Mini Flashcard 7th OL

Front

What do you need to determine velocity of an object?

Back

The speed (distance divided by time) and direction.

Front

If an object changes its speed or direction, it is:

Back

Unbalanced.

Front

What is the average speed of an object for the entire trip if it travels 1 meter in 1 second?

Back

1 m/s.

Front

How many total atoms are in Al₂O₃?

Back

5.

Front

What type of thermal energy transfer causes a hot air balloon to rise?

Back

Convection.

Front

Define velocity.

Back

Velocity is the speed of an object in a given direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is the formula for calculating average speed?

Back

Average speed = Total distance / Total time.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces do.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact.
