How to Calculate and Solve for Reaction: Lift Moves Down | Motion
Last Updated on March 28, 2024
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) and 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, the reaction is 22.4 N.
Calculating the Mass when the Reaction, the Acceleration and the Acceleration due to Gravity are Given
m = R / g – 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, the mass is 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, the acceleration is 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, the acceleration due to gravity is 17.
