How does mass affect gravitational force? The kinetic energy of the mass on a simple pendulum swinging in simple harmonic motion has its maximum value when the displacement is equal to: a) 1/4 the amplitude. b) 1/2 the amplitude. c) the amplitude. d) zero. ...
How does distance affect gravitational force? What is relative mass? How is force expressed in terms of momentum? How does increasing the speed of an object change its momentum? How do you use the formula that relates force, mass and acceleration? Does centripetal force depend on mass? Why i...
Does radius affect gravitational force? Is centrifugal force the force of reaction of centripetal force? Are centripetal force and mass directly related? Is centripetal force and centripetal acceleration the same thing? Does resultant force provide centripetal force? Is the net force the same as the...
e So powerful are some earthquakes that they are believed to alter the Earth’s mass. 答案1、答案是C;句意为不仅白天时间变短了,每年的天数也在变多。2、答案是B;句意为我们很难想象一天可能有32个小时。3、答案是E;句意为一些地震的威力如此之大,以至于人们相信它们会改变地球...
Centripetal force is a type of force that acts towards the center of a circular motion, while gravitational force is the attractive force between two objects with mass. In gravitation problems, the force of gravity is the dominant force, and it acts between two objects, pulling them towards ...
You don't need to know the actual volume, just the mass of the displaced water. All the info to solve for that is given. Mar 9, 2022 #55 rudransh verma Gold Member 1,067 96 Doc Al said: Just call the volume of the stone V. You don't need to know the actu...
resistance, after you let go ofan object the only force on it is the gravitational force. The gravitational force is proportional to the mass of the object. ... The acceleration of an object is proportional to the net force on the object and inversely proportional to the mass of the ...
while weight is the force that gravity exerts on that mass. For instance, a cat has more mass than a mouse, but if you were to weigh them on the moon, the cat may weigh less than the mouse due to the moon's weaker gravitational pull. However, when dealing with water on Earth, the...
Why does the friction force decrease after decreasing applied force? Determine the friction force between the block and the surface. Is sliding friction and friction the same? When is static friction useful? Does mass affect sliding friction?
How do mass and distance affect gravity? A positive charge experiences a force of 0.00065 N from a negative charge of 3.9 x 10^(-4) C when placed 0.0024 meters apart. What is the amount of the positive charge? Comparing the electrostatic force and the gravitational force we can say that...
