At the surface of a certain planet, the gravitational accelera-tion $g$ has a magnitude of $12.0 \mathrm{m} / \mathrm{s}^{2} . \mathrm{A} 13.0-\mathrm{kg}$ brass ball is transported to this planet. What is $(a)$ the mass of the brassball on the Earth and on the planet, and (b) the weight ofthe brass ball on the Earth and on the planet?

a) Mass is independent of gravitational acceleration and hence the mass of the ball is 13.0 $\mathrm{kg}$ on both the Earth and the planet.b) 127$N$, 156$N$

In physics, dynamics is the branch of physics concerned with the study of forces and their effect on matter, commonly in the context of motion. In everyday usage, "dynamics" usually refers to a set of laws that describe the motion of bodies under the action of a system of forces. The motion of a body is described by its position and its velocity as the time value varies. The science of dynamics can be subdivided into, Dynamics of a rigid body, which deals with the motion of a rigid body in the frame of reference where it is considered to be a rigid body. Dynamics of a continuum, which deals with the motion of a continuous system, in the frame of reference where the system is considered to be a continuum.

In physics, orbital motion is the motion of an object around another object, which is often a star or planet. Orbital motion is affected by the gravity of the central object, as well as by the resistance of deep space (which is negligible at the distances of most orbits in the Solar System).

here for party. We know that mass is going to be a mass is independent of the location, so the mass of the ball is going to be equal to 13 kilograms and this would be on any massive body, so on any planet. Now for part B, they want the weight of the ball on earth. Now this is where it's different because it's based on the acceleration due to gravity. So the mass times the acceleration due to gravity on Earth's surface. So 13 points there are kilograms times 9.8 meters per second squared and this is giving us 127 Newtons. Ah, the weight of the borrow on the unknown planet will be the mass of the ball times the gravitational Ah, the acceleration due to gravity on the planet. So 13.0 kilograms and then times 12.0 meters per second squared and this is giving us 156 Newtons. So these would be your two answers for a party. That is the end of the solution.
