Gravity: The primary force acting on the swing is gravity, which pulls the swing down toward the ground. The weight of the person on the swing adds to this gravitational force.

Tension: The swing's ropes or chains exert an upward tension force that counteracts gravity. This tension changes as the swing moves.

Pendulum Motion: A swing can be modeled as a simple pendulum. When the swing is pulled back and released, it moves in an arc due to the gravitational force acting on it.

# data[].attributes.body
Oscillation: The swing undergoes periodic motion, swinging back and forth around a central point (the lowest point of the swing). The time it takes to complete one full cycle is determined by the length of the swing and the acceleration due to gravity.

-We can define " How a swing chair can related to the physic ? "

Where is COG of the swing ?

How does it works ?

What makes the swing stable ?

# data[].attributes.body
A swing operates based on several fundamental principles of physics, primarily involving mechanics and energy.

It's the principle behind the conservation of momentum, but applied to circular motion.

In linear conservation of momentum, mass times velocity is pres

erved absent external forces:

Momentum = m1v1=m2v2

M = mass | V =velocity

Force=m (dv/dt)

Swinging your legs changes inertia .

You can see how the principle works on a swivel chair. lift your legs up and swing them sideways . your body will follow in the same direction.

•Kinetic energy is the fast part of swinging

•Potential energy is the high part of swinging

Kinetic energy : 1/2mv²

Potential energy : mgh

When children pump their legs to swing higher, they’re converting chemical energy from their bodies into mechanical energy, increasing the swing's height and potential energy.

d) The child has more potential energy and less kinetic energy at position X than at position Y

Explanation

1. The total mechanical energy of the child on the swing is the sum of its kinetic energy and gravitational potential energy. At position X, the child is at the highest point of the swing, where the potential energy is at its maximum and the kinetic energy is at its minimum.

2. As the child swings down to position Y, the potential energy decreases while the kinetic energy increases.

3. At position Y, the child has the maximum kinetic energy and the minimum potential energy.

4. Therefore, the child has more potential energy and less kinetic energy at position X than at position Y.
