Приведем выдержку из задания из учебника Биболетова, Бабушис 11 класс, Дрофа:
10 Read the three main laws of mechanics. Match the scientific wording for each law, its main formulas (if they exist) and the explanation thattasks easiest to understand.
Scientific wording
1 Newton’s First Law Any object in a state of invariable motion remains in that state of motion unless a new unbalanced force is applied to it.
- For every action there is an equal and opposite reaction.
or
If you push something, you get pushed back equally hard.
2 Newton’s Second Law The acceleration of a moving object is directly proportional to the value of the net force acting on the object and is inversely proportional to its mass. The vector of the acceleration coincides with the vector of the net force.
- The greater force we apply to the object, the greater acceleration it gets.
3 Newton’s Third Law For every external force that acts on an object there is a force of equal value but in an opposite direction which acts back on the object that exerted the external force.
- If not touched, the object keeps moving in a straight line or remains at rest until a new external force starts acting on it.
