Concept explainers

In nature, every object is attracted by every other object. This phenomenon is called gravity. The force associated with gravity is called gravitational force. The gravitational force is the weakest force that exists in nature. The gravitational force is…

Acceleration Due to Gravity

In fundamental physics, gravity or gravitational force is the universal attractive force acting between all the matters that exist or exhibit. It is the weakest known force. Therefore no internal changes in an object occurs due to this force. On the othe…

Textbook Question

Chapter 12, Problem 69GP

Predict/Calculate When the Moon is in its third-quarter phase, the Earth, Moon, and Sun form a right triangle, as shown in Figure 12-34. Calculate the magnitude of the force exerted on the Moon by (a) the Earth and (b) the Sun. (c) Does it make more sense to think of the Moon as orbiting the Sun, with a small effect due to the Earth, or as orbiting the Earth, with a small effect due to the Sun?

In a judo foot-sweepmove, you sweep your opponent’sleft foot out from under him whilepulling on his gi (uniform) towardthat side. As a result, your opponentrotates around his right footand onto the mat. Figure 10-44shows a simplified diagram ofyour opponent as you face him,with his left foot swept out. Therotational axis is through point O.The gravitational force on himeffectively acts at his center ofmass, which is a horizontal distanced = 28 cm from point O.Hismass is 70 kg, and his rotational inertiaabout point O is 65 kg m2.What is the magnitude of his initialangular acceleration about point O if your pull on his gi is (a) negligibleand (b) horizontal with a magnitude of 300 N and applied atheight h = 1.4 m?

A 225-kg object and a 525-kg object are separated by 3.90 m. (a) Find the magnitude of the net gravitational force exerted by these objects on a 45.0-kg object placed midway between them. 2.37e-7N(b) At what position (other than an infinitely remote one) can the 45.0-kg object be placed so as to experience a net force of zero from the other two objects? ????? m from the 525 kg mass toward the 225 kg mass Is part (a) correct? If not, what is the correct answer? Please, NO handwritten and photoed solutions Please include all formulas used to solve this problem. Please DO NOT put random symbols in equations without an explaination of what the symbols represent.

the mass of saturn is 95.2000 times that of the earth, and its radius is 9.130 times that of earth. calculate the acceleration of gravity at the surface of saturn. (hint: this done as a ratio problem - you do not need to know any actual planet masses).
