Weegy: When considering gravity acceleration and the force of acceleration, [ The direction of the force and the direction of acceleration must be the same as each other must be true. ] User: which one of the following accurately describes the force of gravity? Weegy: The gravity acceleration is in the same direction as the force of gravity. -accurately describes the force of gravity. User: an object with a mass of 120 kilograms is moving at a velocity of 30 m/s. what's its momentum? Weegy: An object with a mass of 120 kilograms is moving at a velocity of 30 m/s. The momentum is 3,600 m/s. 120 * 30 = 3,600 Formula is p = mv, where p is momentum, m is mass in kg and v is velocity in m/s. User: an object has a mass of 13.5 kilograms. what force is required to accelerate it to a rate of 9.5 m/s2? Weegy: 128.25 N force is required to accelerate it to a rate of 9.5 m/s2. force = ma = 13.5 kg * 9.5 m/s2 = 128.25 N User: which of the following accurately describes the differences between the SI and english systems of measurement? Weegy: The SI system, which is based on the metric system, has been more widely adopted than the English system, which is harder to use accurately describes the differences between the SI and English systems of measurement. [ ; ] User: if the velocity of a body changes from 13 m/s to 30 m/s while undergoing constant acceleration, what's the average velocity of the body? Weegy: The average velocity of the body is 21.5 m/s. Initial velocity = 13m/s Final velocity = 30 m/s Average velocity = (13+20)/2 Average velocity = 43/2 Average velocity = 21.5 m/s User: a book, that has a mass of 0.5 kilograms, is pushed across a table with a force of 20 newtons. what is the acceleration of the book? Weegy: The acceleration of the book is 40 m/s User: an object with a mass of 120 kilograms is moving at a velocity of 60 m/s. what is its momentum? Weegy: An object with A mass of 120 kg is moving at a velocity of 60 m/s. Its momentum is ... (More)
