6. What is the acceleration produced by a force of 12 newtons exerted on an object of 3 kg
Answers
Answer:
F=ma
where, F = force
m = mass of the body
a = acceleration
f= 12 N
m= 3 kg
a=?
F = ma
a= F/m
a= 12/ 3
a = 4m/s ²
Explanation:
Given
☛ Force exerted = 12 N
☛ Mass of object = 3 kg
To find
☛ Acceleration produced
Concept
What is force?
Force is what helps to move one body from one point to another.
When, mass and acceleration is given, to find force we have to multiply mass and acceleration.
↑ It's Newton's second law of motion.
Solution
We have ;
➼ Force (F) = 12 N
➼ Mass (M) = 3 kg
Using Newton's second law of motion :-
⟼ Force = Mass × Acceleration
Substituting values in above formula :
☛ 12 = 3 × Acceleration
☛ 12/3 = Acceleration
☛ Acceleration = 4
☛ Acceleration = 4 m/s²
∴ Acceleration produced by body = 4 m/s²
Some more informations :-
☛ Gravitational force, F = (Gm₁m₂)/d²
Where,
⟼ G = Gravitational constant, G = 6.67 × 10-¹¹ m³kg-¹s-²
⟼ m₁ = mass of one body
⟼ m₂ = Mass of 2nd body
⟼ d = Distance
☛ Initial momentum = mu
☛ Final momentum = mv
☛ Change in momentum = (mv - mu/t = ma
