You could use a stopwatch.
The simple pendulum can be used to determine the acceleration due to gravity.
The pendulum swings both ways. Pendulum exercises are used to increase your ROM after shoulder surgery.
Pendulum
Pendulums have been used for thousands of years as a time keeping device in various civilizations. Assuming that it is only displaced by a small angle, a pendulum wall have a period of 2pi*√(L/g) where L is the length of the pendulum and g is the acceeleration due to gravity, normally 9.81m/s². One of the cool things about pendulums is that if one is made with a length of one meter, it will have a period of 2.00607 seconds, meaning it will take just slightly more than one second to swing from one side to another.
A Foucault pendulum is a pendulum with a large length which is free to oscillate in any vertical plane. At the equator, the plane of oscillation remains fixed relative to the earth. Elsewhere, the plane of oscillation rotates, at a speed that is related to the latitude of the location. In Paris, where Foucault's pendulum is located, the plane of the pendulum's oscillation moves at approx 11 degrees per hour. This movement can be used to tell the time.
Measure the length and the period
A protractor is used to measure angles.
A stopwatch could be used.
The term to describe the duration of arcs of a pendulum is called period. This is how long the pendulum takes to move through an entire cycle.
It may be possible in theory but for all practical purposes... it can't
the pendulum is used to tell time
Focault's Pendulum refers to a large pendulum which is used to demonstrate or measure the rotation of the Earth. Cleopatra's Needle can refer to any of three ancient Egyptian obelisks which were transported to London, Paris and New York and re-erected as monuments.
The time period of a simple pendulum is calculated using the following conditions: Length of the pendulum: The longer the length of the pendulum, the longer it takes for one complete back-and-forth swing. Acceleration due to gravity: The time period is inversely proportional to the square root of the acceleration due to gravity. Higher gravity results in a shorter time period. Angle of displacement: The time period is slightly affected by the initial angle of displacement, but this effect becomes negligible for small angles.
Gravity can be measured many ways. You can drop an object and observe how it falls and determine the objects acceleration. With that in hand you can then calculate the force required, and measure gravity that way. You can use a scale, and determine the force acting upon the object placed on it to compress the springs a certain distance, or deflect it a certain distance (depending on the scale's design). A pendulum can be used to measure gravity. The period of a pendulum is directly influenced by the magnitude of the accelerating force (gravity) you can measure altitude with a sensitive pendulum. As gravity is a force, any method you would use to determine the force of one object exerting upon another would work to measure gravity.
Our Physics class calculated that the height of the dome inside the cathedral is approximately 16m. We used the relationship between the period of a pendulum (incense thurible) and the length of the pendulum.
