## How do you find the g of a pendulum graph?

The constant g can be calculated by dividing 39.5 (4p�) by the slope: g = 39.5/slope.

- g = 39.5/_______ = ____________ The value of g on planet Earth is roughly 9.8 m/s�.
- percentage error = (your value for g – 9.8)/9.8 = _____________
- Question: What will the period be for a pendulum with a length of 4 meters.

## How do you calculate period T?

The formula for the period T of a pendulum is T = 2π Square root of√L/g, where L is the length of the pendulum and g is the acceleration due to gravity.

**How do you find the g from L or T2 graph?**

The slope of the T² vs l graph of a pendulum gives the measured value of g (acceleration due to gravity).

- The time period T of a simple pendulum is given by the formula T = 2π √(l/g). Here l is the length of the pendulum.
- Squaring both the sides, we get T² = 4π² l/g.

**What does the slope of graph between T2 and L of a pendulum give us?**

The slope of the T² vs l graph of a pendulum gives the measured value of g (acceleration due to gravity).

### What does the slope of T2 vs L represent?

The slope of T2 vs l graph is found to be constant at any place and is equal to 4π2g where g is the acceleration due to gravity at that place. Explanation: In a T2 vs l graph, with T2 in the Y-axis and l in th X-axis, slope = T2l.

### How does the length of string affect a pendulum period?

The length of the string affects the pendulum’s period such that the longer the length of the string, the longer the pendulum’s period. This also affects the frequency of the pendulum, which is the rate at which the pendulum swings back and forth.

**How do you find the length of a seconds pendulum from a LT 2 graph?**

Plot a graph between l (column, 2b) and T2 (column 5) by taking Z along X- axis and T2 along Y-axis. The graph comes to be a straight line. From this graph, for T2 = 4, l comes to be 100 cm. Hence for seconds pendulum (T = 2 s) length comes to be 100 cm.

**What is g in a graph?**

The total graph T(G) of a graph G has as its vertices the elements (vertices or edges) of G, and has an edge between two elements whenever they are either incident or adjacent. The total graph may also be obtained by subdividing each edge of G and then taking the square of the subdivided graph.
