12 Questions
How was the phenomenon of gravitation discovered?
Sir Isaac Newton discovered the force of gravity by observing an apple fall from a tree.
What led Newton to conclude that the Earth attracts objects towards its center?
Newton observed that the apple fell vertically downward, leading him to infer that the Earth must exert an attractive force directed towards its center.
Why did Newton question why apples fall vertically downward and not at an angle to the vertical?
Newton questioned this to understand the nature of the force causing objects to fall towards the Earth.
What is the direction of the attractive force exerted by the Earth on objects near its surface?
The attractive force exerted by the Earth on objects is directed towards the center of the Earth.
In what direction does the attractive force of the Earth act on objects like the apple Newton observed?
The attractive force of the Earth acts from the object towards the center of the Earth.
What did Newton conclude about the direction of the force attracting the apple towards the Earth?
Newton concluded that the attractive force must be directed towards the center of the Earth.
What did Newton question regarding the force of gravitation acting on apples?
Whether it could also act on objects at greater heights or distances, like the moon, planets, and the Sun.
Why is a force necessary to change the speed and direction of motion of an object?
To alter the object's velocity, either in terms of speed or direction.
What concept does Figure 1.1 illustrate?
The gravitational force between the earth and the moon.
In which direction does the force act on an apple on the tree according to the figure?
Towards the center of the Earth, perpendicular to the apple's position on the surface.
What did Newton propose in his laws of motion?
Laws that explain how forces affect the motion of objects.
How can ICT be used to enhance learning about gravitational forces?
By collecting videos and presentations about the gravitational force of different planets.
Explore the effects of forces on objects, different types of forces, and delve into the gravitational force, a universal force that acts between all objects in the universe. Learn about the discovery of this force and its significance in understanding the motion of celestial bodies.
