I need help
what force is needed to make a ball fall on earth if it had a mass of 13kg

I'd appreciate if someone could help me thank you ​

Sagot :

Newton's second law allows finding the answer for the force that attracts the body is 127.4N

Newton's second law indicates that the force that is the interaction between two bodies is directly proportional to the product of the mass and the acceleration.

            F = m a

Where the bold letters indicate vectors, F is the force, m the mass, and the acceleration of the body.

When a body is close to the Earth there is an interaction between the body and the planet, we call this interaction weight, it is given by the relationship

           W = m g

Where W is the force called weight, m ​​the mass of the body and g the acceleration of the body, which in this case is called the gravity acceleration   (g = 9.8 m / s²)

They indicate that the mass of the body is m = 13 kg, let's calculate the weight

           W = 13  9.8

           W = 127.4 N

In conclusion using Newton's second law we can find the answer for the force that attracts the body is 127.4N
