What type of motion is a seesaw?

Motion of a child in a sea saw is an oscillatory motion. This is because the child goes up and down at a continuous speed at a particular point of time.

Why are seesaws called seesaws?

Name origin and variations Seesaw, or its variant see-saw, is a direct Anglicisation of the French ci-ça, meaning literally, this-that, seemingly attributable to the back-and-forth motion for which a seesaw is known. The term may also be attributable to the repetitive motion of a saw. Thus “scie-saw” became “see-saw”.

How does a see-saw work?

A seesaw is a specific type of lever; it consists of a long beam attached to a pivot called the fulcrum. As soon as you put weight on one end by sitting on one side of the beam it drops to the ground. This is because the force of gravity is acting on the weight of your body, pulling it and the beam down.

What is pendulum motion?

Pendulum motion basically depicts the motion of a mass hanging from a string that moves back and forth. The variables in pendulum motion are the mass, the length of the string, and the location, which is measured by an angle. Forces acting on the mass in pendulum motion are tension and gravity.
