Question

Identify what is being described in each of the following statements.

______1. A vector quantity, to quantity a push. It is any influence on the motion of an object.

______2. A force that keeps on object "stuck" on a surface and prevents its motion.

______3. Force that oppose the motion.

______4. The product of force and displacement.

______5. The energy in motion an d it is the energy possesed by an object that is moving.

______6. The rate of doing work.

______7. It states that in the absence of non-conservation forces, the initial and final energies of a system reamin constant.

_____8. This law stated that in an isolated system, the total momentum of the particles constituting the system remains constant.

______9. When a rigid body is a solid composed of a collection of particles. These particles remain static relative to each other and relative to the axis of rotation.

______10. For any rigid body rotating about a fixed axis, suppose that the angular acceleration is constant.

Answer 1

1) Force. A vector quantity, to quantity a push. It is any influence on the motion of an object.

2) Static friction. A force that keeps on object "stuck" on a surface and prevents its motion.

3) Friction. Force that oppose the motion.

4) Work. The product of force and displacement.

5) Kinetic energy. The energy in motion and it is the energy possesed by an object that is moving.

6) Power. The rate of doing work.

7) Law of conservation of mechanical energy. It states that in the absence of non-conservation forces, the initial and final energies of a system remains constant.

8) Law of conservation of momentum. This law stated that in an isolated system, the total momentum of the particles constituting the system remains constant.

9) Position of the rigid body. When a rigid body is a solid composed of a collection of particles. These particles remain static relative to each other and relative to the axis of rotation.

10) Angular velocity. For any rigid body rotating about a fixed axis, suppose that the angular acceleration is constant.
