## What happens to the kinetic energy and potential energy of the pendulum as it swings from its highest to lowest position?

The potential energy decreases while the kinetic energy increases.

## Why did the pendulum stop swinging Where did the energy go?

The main reason the pendulums stop is due to air friction and the friction at the point of rotation. To see a pendulum that removes one of these sources of friction, you can see a Coriolis force clock. These are pendulums that swing but instead of being on a pivot point, they are held up magnetically.

## What affects the swing of a pendulum?

The forces of gravity, the mass of the pendulum, length of the arm, friction and air resistance all affect the swing rate.

## What happens when the suspended mass is doubled?

happens when the suspended mass is doubled? The period becomes square root 2 times as long. The mass does not affect the period so it stays the same if the mass is doubled.

## How do you find the mass and distance of a spring constant?

The formula to calculate the spring constant is as follows: k= -F/x, where k is the spring constant. F is the force and x is the change in spring’s length.

## Does the spring constant change on Jupiter?

The spring constant stays the same, assuming that Hooke’s law can be applied for every stretching of the spring. If a mass is attached to the spring then in the gravity field of the Moon, the Earth, or, say, Jupiter then the spring still obeys Hooke’s law when stretched by the mass.

## Does gravity affect spring constant?

The period of oscillation depends on the restoring force and the inertia (mass) which is oscillating. Gravity is a constant force. Although gravity affects what the equilibrium extension will be, it is not the restoring force, so it does not affect the period of oscillation of a mass on a spring.

## Does spring constant change with compression?

The proportional constant k is called the spring constant. When a spring is stretched or compressed, so that its length changes by an amount x from its equilibrium length, then it exerts a force F = -kx in a direction towards its equilibrium position.
