I. Read the text. Choose the most suitable heading from the list (a-g) for each part (1-5) of the text. There are two extra headings which you do not need to use.

A. The Newton’s Two Laws.

B. The Main Principle of Mechanics.

C. The Equality of Forces.

D. Basic Characteristics of the Laws of Mechanics.

E. Types of Mechanics.

F. The Change in the State of Motion.

G. The First Law of Mechanics.

II. Read the text. For statements (6-15) choose “True” if the statement is true according to the text, “False” if the statement is false:

  1. Mechanics deals with the motion of objects under the action of forces.

  2. The intrinsic properties of bodies are always taken into account in classical mechanics.

  3. In classical mechanics the Earth and the Sun are considered as points.

  4. Classical mechanics states on Newton’s laws of motion.

  5. The first law considers only uniform motion of a body.

  6. Mechanics concentrates on motion as a physical phenomenon.

  7. The product of the mass of a body and its velocity is the net force.

  8. During the interaction of two particles the forces are equal both in magnitude and direction.

  9. The laws of motion allow defining the future motions of particles.

  10. The laws of mechanics include some symmetry properties.

III. Read the text. For questions (16-20) choose the correct answer (a, b, c or d).

16) Classical mechanics …

a) is quite different from the mechanics of a solid body.

b) is the basis for its branches.

c) studies the velocity of a body.

d) gives the explanation of magnitude.

17) The mechanics of deformable solids also …

a) is capable to make the body move.

b) studies the Earth and the Sun.

c) concerns fluids at rest and in motion.

d) is of great interest among scientists.

18) Newton’s Laws …

a) present quantum mechanics.

b) explain everything in physics.

c) are basic for those who study motion.

d) equate the net force of an object.

19) According to the Newton’s third law the magnitude of the forces of interacting bodies…

a) is the same.

b) is different.

c) is almost the same.

d) remains the same.

20) One of the symmetries of mechanics …

a) is at basic levels of physics.

b) is present only in quantum mechanics.

c) was described by Newton.

d) is the invariance.

IV. Match (21-30) with their definitions (a-l). There are two definitions that you do not need to use.
