# How do you calculate the mass of an Atwood Machine?

## How do you calculate the mass of an Atwood Machine?

m2a = T − m2g (2) where T is the tension in the string and g is the acceleration due to gravity (g = 9.8 m/s2). Figure 2: Free body diagrams for the masses of the Atwood Machine. The tension T is shown in blue and the weight of each mass W is in green.

## How do you solve the Atwood Machine problem?

The machine typically involves a pulley, a string, and a system of masses. Keys to solving Atwood Machine problems are recognizing that the force transmitted by a string or rope, known as tension, is constant throughout the string, and choosing a consistent direction as positive.

What’s the formula of tension?

Tension Formula. The tension on an object is equal to the mass of the object x gravitational force plus/minus the mass x acceleration. T = mg + ma. T = tension, N, kg-m/s2.

### Do the two masses have the same magnitude acceleration Why?

The total acceleration of the system is the same for both masses; M1 accelerates upward at the same rate as the downward acceleration of M2 because they are tied together. We can treat the whole system as a single mass, M = M1 + M2.

### What is the tension formula?

Tension formula is articulated as. T=mg+ma. Where, T= tension (N or kg-m/s2) g = acceleration due to gravity (9.8 m/s2)

What is the formula for tension?

## How do you find the mass of an object in a pulley?

Calculate the tension on both sides of the pulley system using a calculator to solve the following equations: T(1) = M(1) x A(1) and T(2) = M(2) x A(2). For example, the mass of the first object equals 3g, the mass of the second object equals 6g and both sides of the rope have the same acceleration equal to 6.6m/s².

## Do the two masses have the same acceleration Why?

the two accelerations turn out the same. In essence, the larger mass gets a larger force from the gravitational field but it needs a alrger force to make it accelerate. The two effects cancell and all masses tend to accelerate the same in the same gravitational field.

What is value of g in physics?

In the first equation above, g is referred to as the acceleration of gravity. Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2.
