Question

The magnitude of the force associated with the gravitational field is constant and has a value f. A particle is launched from point b with an initial velocity and reaches point a having gained u0 joules of kinetic energy. A resistive force field is now set up such that it is directed opposite the gravitational field with a force of constant magnitude 12f. A particle is again launched from point b. How much kinetic energy will the particle gain as it moves from point b to point a?.

Answer 1

The particle will have an energy of 12U0. A particle travels at an initial velocity from point B to point A, gaining U0 joules of kinetic energy along the way. The constant force at this point is equal to 12F.

Does 9.8 represent gravity?

The acceleration which gravity gives to objects falling freely serves as a gauge of its strength. The gravity's acceleration at Earth's surface is approximately 9.8 meters (32 feet) per second every second.

What is a good illustration of gravity?

The following are a few instances of the power of gravity: the energy holding the gases inside the sun. the power behind a ball's descent after being thrown into the air. the force that makes an automobile coast down even when the gas is not depressed.
