Atwood Machine Lab

• This device is used to calculate force and tension in string and to verify the laws of motion of objects under constant acceleration
• We can calculate the tension in string
• We can calculate the constant acceleration of bodies
• We can find the value of gravitational acceleration g.

Acceleration in body is $$a=\frac{m_1}{m_1+m_2}g$$ Tension in string is $$T=\frac{m_1{m}_2}{m_1+m_2}g$$
