I don't know of any that relate the period, radius and the value of g
Draw a free body diagram with the pendulum at some angle to the vertical. Show the forces acting on the bob. Assign identifiers (algebraic variables) to the angle, the mass, etc. Obtain an equation for the acceleration.Klymene15 said:@tadchem: Um... The link only said "It works!" What works, I don't know...
@Doc Al: I'm looking to learn how to do it, not simply find an equation.
Did you even attempt to Google it? Or use the excellent hyperphysics reference? (Or your text.) Full derivations (similar to what haruspex outlined) are readily available.Klymene15 said:@Doc Al: I'm looking to learn how to do it, not simply find an equation.
The equation for solving for g is g = F/m, where g represents the acceleration due to gravity, F represents the force applied, and m represents the mass of the object.
To solve for g, you must divide the force applied (F) by the mass of the object (m). This will give you the value of the acceleration due to gravity (g).
Solving for g allows us to understand the effects of gravity on objects and how they move. It is an important concept in physics and is used in many real-world applications such as calculating the trajectory of projectiles and designing roller coasters.
The units for g in the equation are meters per second squared (m/s²). This represents the rate of change of velocity over time due to the force of gravity.
Yes, the value of g can change depending on the location and elevation on Earth. It also varies slightly due to factors such as the rotation of the Earth and the density of the Earth's crust. However, for most practical purposes, the average value of g is used, which is approximately 9.8 m/s².
