What acceleration imparts a force of 20N to a body with a mass of 2 kg?
| August 16, 2021 | education
m = 2 kg.
F = 20 N.
a -?
According to 2 Newton’s law, the acceleration of a body a is directly proportional to the force F, which acts on the body, and inversely proportional to the mass of the body m: a = F / m.
This means that how many times the force F, which acts on the body, is increased, the body’s acceleration a will increase by how many times. How many times the force is reduced, the acceleration of the body will decrease.
The number of times the body mass m is increased, the number of times the acceleration of the body a decreases. How many times the body weight is reduced, the acceleration of the body will increase.
a = 20 N / 2 kg = 10 m / s2.
Answer: the force imparts acceleration to the body a = 10 m / s2.
