FINAL REVIEW

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

During which time interval is an object accelerating if it is moving faster at the end of the interval than at the beginning?

Back

The object is accelerating during the time interval of 11-15 seconds.

Front

What causes lightning to occur?

Back

Lightning occurs due to the attraction between positively charged clouds and negatively charged ground.

Front

Which element is most likely to give up a single electron?

Back

Lithium (Li) is most likely to give up a single electron due to its position in the periodic table.

Front

What is a noble gas?

Back

A noble gas is an element that has a full valence shell of electrons, typically eight, making it stable and unreactive.

Front

Which element has eight valence electrons?

Back

Neon (Ne) has eight valence electrons, making it a noble gas.

Front

What is the relationship between speed and acceleration?

Back

Acceleration is the change in speed over time; if speed increases, the object is accelerating.

Front

What does it mean for an object to be in free fall?

Back

An object in free fall is only under the influence of gravity, with no other forces acting on it.

Front

How does a ramp affect the acceleration of an object?

Back

A ramp can increase the acceleration of an object as it moves downwards due to the force of gravity acting on it.

Front

What is the significance of oppositely charged particles?

Back

Oppositely charged particles attract each other, which is fundamental in understanding electric forces and phenomena like lightning.
