If an object has a mass of 10 kilograms, how much does it weigh in Newton’s?

Explanation:

Weight is the earth pull of an object to itself.

The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity.

The unit of weight is Newton and it is a vector quantity, it is directed downward vertically.

W= mg.

Where g varies but the gravity on earth is 9.81m/s² approximately.

Given that,

m=10kg, g=9.81

Then,

W=mg

W=10×9.81

W=98.1N

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
