Web15 mei 2024 · Explanation: The mathematical expression for the kinetic energy is given by : According to given condition, if the speed of an object doubles, v' = 2v. So, kinetic … WebThe law says that the force is proportional to the amount of charge on each object and inversely proportional to the square of the distance between the objects. If we double the charge q 1, for instance, then the force is doubled. If we double the distance between the objects, then the force between them decreases by a factor of 2 2 = 4 .
Web26 jul. 2024 · If an object is lifted, work is done against the force of gravity. When work is done energy is transferred to the object and it gains gravitational potential energy. If the … WebThe kinetic energy of an object with mass m and which has a speed of v is given by (1/2)*m*v^2. The change in the kinetic energy of the object as the speed changes is …
Web8 nov. 2024 · The correct answer is to increase by four times. The momentum of an object is equal to the product of the mass of the object and its velocity. Key Points Let us display this with p. Its vector sign is in the direction of velocity. Its SI unit is "kg-meter / second". http://problemsphysics.com/momentum/questions.html
