Speed Есеп №1 Determine the force of gravitational attraction between the earth (m = 5.98 x 10 24 kg) and a 70-kg physics student if the student is standing at sea level, a distance of 6.38 x 10 6 m from earth's center. Задача №2 Suppose that two objects attract each other with a gravitational force of 16 units. If the distance between the two objects is doubled, what is the new force of attraction between the two objects? Answer: F = 4 units If the distance is increased by a factor of 2, then force will be decreased by a factor of 4 (2 2 ). The new force is then 1/4 of the original 16 units. F = (16 units ) / 4 = 4 units Сабақ қорытындысы 69 Plan 26 Grade: 9 The theme of the lesson: Mass and weight.
