The image above represents reaction: lift falls freely.

To compute for reaction: lift falls freely, two essential parameters are needed and these parameters are **mass (m) **and **acceleration due to gravity (g).**

The formula for calculating reaction: lift falls freely:

R = mg

Where;

R = Reaction

m = Mass

g = acceleration due to gravity

Let’s solve an example;

Find the reaction when the mass is 30 and acceleration due to gravity is 9.8.

This implies that;

m = Mass = 30

g = acceleration due to gravity = 9.8

R = mg

R = 30 x 9.8

R = 294

Therefore, the **reaction **is **29****4 N.**

**Calculating the Mass when the Reaction and the Acceleration due to Gravity is Given.**

m = ^{R} / _{g}

Where;

m = Mass

R = Reaction

g = acceleration due to gravity

Let’s solve an example;

Find the mass when the reaction is 40 and the acceleration due to gravity is 9.8

This implies that;

R = Reaction = 40

g = acceleration due to gravity = 9.8

m = ^{R} / _{g}

m = ^{40} / _{9.8}

m = ^{40} / _{9.8}

m = 4.08

Therefore, the **mass **is **4.08****.**

**Calculating the Acceleration when the Reaction, the Mass and the Acceleration is Given.**

g = ^{R} / _{m}

Where;

g = acceleration due to gravity

R = Reaction

m = Mass

Let’s solve an example;

Find the acceleration due to gravity when the reaction is 30 and the mass is 5.

This implies that;

R = Reaction = 30

m = Mass = 5

g = ^{R} / _{m}

g = ^{30} / _{5}

g = 6

Therefore, the **acceleration due to gravity **is **6****.**
