Why are pushes given to a playground swing

What if two students leaned against each other? Now ask your students to design the best ride ever! Challenge the students to choose one piece of playground equipment and brainstorm ways to improve it or invent an entirely new piece of equipment. Invite students to sketch their designs on paper, adding descriptions of what each invention does and explaining why it is the best ride ever.

Remind students to use as many physics words in their descriptions as possible! Create a List. List Name Save. Rename this List. Rename this list. List Name Delete from selected List. Save to.

Swinging Forces Materials Needed: Access to at least one swing Plain, white paper, one piece per student Pencils, pens, or markers Science Concept : What makes a swing swing?

Air Resistance Test Materials Needed: Access to climbing equipment or chairs for students to stand on Plain, white paper, one piece per student and two pieces for the demonstration Science Concept: Air resistance — the push of air against a moving object — can have a surprising effect on gravity.

Seesaw Lever Lift Materials Needed: Access to at least one seesaw Heavy objects for students to practice lifting, such as big dictionaries or plastic bins Science Concept : It is easy to lift a piece of paper or a feather, but could you lift a sack of rocks?

Problem 25 Easy Difficulty Why are pushes given to a playground swing more effective if they are given at certain, regular intervals than if they are given at random positions in the swing's cycle? Answer words View Answer. Topics No Related Subtopics. Holt Physics Chapter 13 Sound. Discussion You must be signed in to discuss. Top Educators.

A guitar produces sound entirely by vibration. In an acoustic guitar when you pluck a string, it vibrates and transmits the sound energy into the hollow wooden body of the guitar, making it and the air inside resonate and amplifying the sound making it considerably louder.

Whereas in an electric guitar when the musician strikes the string, it oscillates and the electromagnetic device in the guitar turns this oscillation into an electric signal that is sent to the amplifier. The amplifier sends oscillations on to the speaker. If the frequency of the speakers matches the vibration of the guitar, it results in sound which is called audio feedback.

The pendulum works on the same principle as the swing. If we push the pendulum it will move back and forth. Continuous pushing at the regular time intervals will cause an increase in the motion of the pendulum. If regular pushes are given to the pendulum, its motion can be built enormously. Have you ever watched or heard about shattering of a wine glass in an orchestra? If yes, then this is all due to the phenomenon of resonance. The natural frequency of glass or any other object is determined by its shape and composition.

However, the full transfer of energy can cause shattering of glass.
