Задача
Read the questions and give the answers as quickly as possible.
Blitz:
- Can the weight and the mass of one and the same object have different values?
- Do the weight of an object and the gravity force which acts on it have the same or opposite directions?
- Which of the formulas should be applied to find out the gravity force on the Earth?
- a) $$V=\frac{S}{t}$$
- b) $$F=mg$$
- c) $$F=ma$$
- What is the value of the gravitational constant?
- What do we call a unit to measure the force?
Подробный ответ
- Yes, they can. Weight depends on gravity, while mass does not.
- They have the same direction.
- b) F = mg.
- The gravitational constant is 6.67 × 10-11 N·m2/kg2.
- A unit to measure force is called a newton.
