All the heavenly bodies in space like the moon, the planets and the stars also exert an attractive force on objects. The bigger and heavier a body is, the greater is its force of gravity. Thus, since the moon is a smaller body than the Earth, the force it exerts on an object at it...
The scientist explained to us that the force of gravity2. What scientists think is that the Earth became differentbecause of small plants growing in the water on its sur-face.3. It is obvious to the students that they should get wellprepared for their future.4. The last time we had grea...
The gravitational force acting on an object at the Earth's surface is called the weight of the object. All the heavenly bodies in space like the moon, the planets and the stars also exert an attractive force on objects. The bigger and heavier a body is, the greater is its force of gr...
G-force, also known as gravitational force, is a term used to describe the force of gravity acting on an object. It is a measurement of the acceleration experienced by an object due to gravity and is typically measured in units of acceleration. G-force is an important concept in physics,...

We have all experienced the force of gravity. It is what happens to you when you jump up into the air. Disappointingly, we tend to fall right back down to the ground. But what if we could switch gravity off? What will happen if the gravity vanishes? Buckey, an astronomer, says that...
What was the purpose of the experiment? A. To study the force of gravity. B. To understand how friction affects the movement of objects. C. To measure the mass of the wooden block. D. To test the strength of the spring scale.
