The image above represents reaction: lift moves down. To calculate reaction: lift moves down, three essential parameters are needed and these parameters are **mass (m), acceleration (a)Â **andÂ **acceleration due to gravity (g).**

The formula for calculating reaction: lift moves down:

R = m(g – a)

Where;

R = Reaction

m = Mass

g = acceleration due to gravity

a = Acceleration

Let’s solve an example;

Find the reaction when the mass is 28, acceleration is 9 and acceleration due to gravity is 9.8.

This implies that;

m = Mass = 28

g = acceleration due to gravity = 9.8

a = Acceleration = 9

R = m(g – a)

So, R = 28(9.8 – 9)

R = 28(0.80)

R = 22.4

Therefore, theÂ **reactionÂ **is **22****.4 N.**

**Calculating the Mass when the Reaction, the Acceleration and the Acceleration due to Gravity are Given**

m = ^{R} / _{gÂ – a}

Where;

m = Mass

R = Reaction

g = acceleration due to gravity

a = Acceleration

Let’s solve an example;

Find the mass when the reaction is 42, the acceleration is 8 and the acceleration due to gravity is 9.8

This implies that;

R = Reaction = 42

g = acceleration due to gravity = 9.8

a = Acceleration = 8

m = ^{R} / _{g – a}

Then, m = ^{42} / _{9.8 + 8}

m = ^{42} / _{17.8}

m = 2.359

Therefore, theÂ **massÂ **isÂ **2.359.**

**Calculating the Acceleration when the Reaction, the Mass and the Acceleration due to Gravity are Given**

a = g – (^{R} / _{m})

Where;

a = Acceleration

R = Reaction

m = Mass

g = acceleration due to gravity

Let’s solve an example;

Find the acceleration when the reaction is 35, mass is 19 and acceleration due to gravity is 9.8.

This implies that;

R = Reaction = 35

m = Mass = 19

g = acceleration due to gravity = 9.8

a = g – (^{R} / _{m})

So, a = g – (^{35} / _{19})

a = 9.8 – 1.84

a = 7.96

Therefore, theÂ **accelerationÂ **isÂ **7.96.**

**Calculating the Acceleration when the Reaction, the Mass and the Acceleration are Given**

g = (^{R} / _{m}) + a

Where;

g = acceleration due to gravity

R = Reaction

m = Mass

a = Acceleration

Let’s solve an example;

Find the acceleration due to gravity when the reaction is 40, the mass is 4 and the acceleration is 7.

This implies that;

R = Reaction = 40

m = Mass = 4

a = Acceleration = 7

g = (^{R} / _{m}) + a

Then, g = (^{40} / _{4}) + 7

g = 10 + 7

g = 17

Therefore, theÂ **acceleration due to gravityÂ **isÂ **17.**
