Work in pairs. Read the physics vocabulary and their definitions. Suggest the Russian equivalents for them.

• acceleration — change in speed or direction
• state of motion — characteristics of the way an object moves in the chosen coordinate system
• state of rest — the form of existence when the object does not move (in the chosen coordinate system)
• inertia — tendency to resist any changes in state of motion
• vector — something which has quantity and direction
• velocity — vector value of the speed
• frictional force — the force that acts upon the moving object in the movement in the opposite direction
• the universal gravitational constant — universally characterises the intrinsic strength of the gravitational force
• gravitational acceleration — changing of speed due to gravity on the Earth’s surface
• equilibrium — the position in which all forces are balanced
• net force — the vector sum of all the forces that act on the object
• elastic force — a force arising from a deformation of an object
