2024 Fall Benchmark Review

Front

What does Newton's Third Law of motion state about action and reaction forces during a collision?

Back

In every collision, the action and reaction forces are always equal and opposite.

Back

Digital signal.

Front

What happens to an object in acoustic levitation if the amplitude of the sound waves is lowered?

Back

The object will no longer float because the energy will decrease.

Front

What does a free body diagram of an object moving at constant speed illustrate about the forces acting on it?

Back

It shows that all forces are balanced, meaning they are equal and opposite in all directions.

Front

In a generator, what type of energy is converted to electrical energy?

Back

Mechanical energy.

Front

What is the principle behind acoustic levitation?

Back

It uses sound waves to suspend objects in the air.

Front

How do balanced forces affect the motion of an object?

Back

Balanced forces result in no change in the object's motion, keeping it at a constant speed.

Front

What is the difference between digital and analog signals?

Back

Digital signals have discrete values, while analog signals have continuous values.

Front

What is the significance of equal and opposite forces in Newton's Third Law?

Back

They ensure that the total momentum of a system is conserved during interactions.

Front

What role does amplitude play in acoustic levitation?

Back

Amplitude determines the energy of the sound waves; lower amplitude reduces the energy available to suspend the object.
