What is a pendulum?

• A type of spring

• A mass hung from a string from a fixed object

• A type of lever

• A fixed object on a surface

Imagine you're in a science museum, observing a large pendulum swinging back and forth. What is the term used to describe the mass at the end of this pendulum?

• Pendulum arm

• Pendulum string

• Pendulum bob

• Pendulum pivot

Imagine a grandfather clock with a pendulum. When the pendulum stops swinging and reaches its resting position, how does it hang?

• At an angle

• Horizontally

• Vertically (straight down)

• In a circular arc

Imagine a grandfather clock with a pendulum. What kind of motion does the pendulum exhibit when it is pulled to one side and released?

• Periodic motion

• Simple harmonic motion

• Linear motion

• Random motion

What is the definition of "Period" in the context of a pendulum's motion?

• The maximum displacement of the pendulum from its rest position

• The number of complete swings the pendulum makes in a set period of time

• The time that the pendulum takes to complete one full swing

• The highest and lowest points of the pendulum's path

What does "Amplitude" refer to in the context of ocean waves?

• The time it takes for a wave to travel from one peak to the next

• The number of waves passing a fixed point in a set period of time

• The highest and lowest points of the waves on a graph

• The maximum height of a wave from its rest position

How is "Frequency" defined in the context of radio stations?

• The maximum volume level of the broadcast

• The duration it takes for a radio station to complete a full playlist cycle

• The highest and lowest points of the signal strength on a graph

• The number of complete signal cycles occurring in a set period of time

Imagine a child swinging on a swing set. What happens to the velocity of the swing as it moves from its highest point back down to its lowest point?

• The velocity remains the same.

• The velocity decreases.

• The velocity increases.

• The velocity becomes zero.

What happens to a child's speed on a swing as they reach the highest point of the swing?

• It gains velocity.

• It remains constant.

• It becomes zero.

• It loses velocity.

Imagine you're at the beach, watching the ocean waves. How can these waves be described?

• A. As static objects that do not move

• B. As disturbances that travel through the ocean from one location to another

• C. As forms of energy that remain in one place

• D. As patterns that do not involve the transfer of energy
