How is the center of the gravity determined when an object is at rest or in motion?
If the object is a thin lamina with uniform thickness (e.g. a piece of paper), the the centre of gravity of the object is at its geometrical centre. It can be determined by suspending a load (e.g. pendulum) on an edge of the lamina twice and the point where the plumb lines intersect is the centre of gravity.

Is the weight of an object not affected by gravity?
weight is defined as the product of mass and gravity constant. as the value of gravity changes weight is also changed
What is the pulling force that the planet earth has?
The pulling force that the planet Earth has on objects is known as gravity. It is responsible for keeping objects on the surface of the Earth and is determined by the mass of the Earth and the distance of the object from its center.
What force always tends to slow the motion of an object on a surface?
Friction or gravity .
What are the ways in locating the center of gravity of irregularly shaped objects?
You can locate the center of gravity of irregularly shaped objects by using the plumb line method, which involves suspending the object and letting it come to rest naturally. Another method is to use physical calculations based on the object's mass distribution to determine the center of gravity. Computer simulations can also be used to estimate the center of gravity for complex shapes.
Is the path that a thrown objects follows?
The path that a thrown object follows is called a projectile path, which is determined by the initial velocity and angle of the throw. The object moves in a curved trajectory, influenced by gravity pulling it downward. The shape of this path is typically a parabolic curve.
How center of gravity determines whether the objects is at rest or in motion.?
The centre of gravity does not, by itself, determine whether an object is at rest or in motion. The location of the centre of gravity, relative to where the object is supported, can contribute one of many forces that can act on the object. And it is is the [vector] sum of these forces which determines whether the object remains at rest or in uniform motion.
How can gravity change the motion of an object?
Gravity can change the motion of an object by pulling it towards a massive body, such as a planet or star. This force causes the object to accelerate towards the center of mass of the massive body, changing its speed and direction of motion. The greater the mass of the object or the closer it is to the massive body, the stronger the gravitational force and the greater the impact on the object's motion.
Is the force of gravity on an object at rest in free fall and the same object horizontally?
Yes. The force of gravity is the same, 9.8m/s2, whether an object is at rest, in vertical motion, or horizontal motion, because the force of gravity is due to the mass of the earth and not to the motion of any object. The force of gravity does decrease slightly with altitude, as distance from the center of the earth increases.
How do gravity and friction affects the motion of an object?
The mass of The Earth is determined by the size. and we have less gravity. which controls movement in the object, and in Newton's laws it explains that every Action has a reaction so what you do to an object will have an effect on it.
How do you determine the centre of gravity of an irregular object?
The center of gravity of an irregular object can be determined by finding the point where the object would balance perfectly in any orientation. This can be done by supporting the object at different points and adjusting until it is balanced. The center of gravity is typically the point where all these balancing points intersect.
If an object is to stand firm and not tip over what must be its centre of gravity?
The center of gravity of an object must be directly above its base of support in order to prevent tipping over. If the center of gravity is outside of the base of support, the object will be unstable and likely to tip.
What are changes in the motion of an object determined by?
Changes in the motion of an object are determined by the forces acting on it, such as gravity, friction, and applied forces. These forces can cause the object to speed up, slow down, change direction, or remain at a constant velocity. The object's mass and the net force acting on it also play a crucial role in determining its motion.
Where does an object center of gravity always lie?
It is always different depending on the object. For example a female humans' center of gravity is in the hip. as a male humans' center of gravity is in the chest. But once you have found the center of gravity in an object the center of gravity should be the same in every object like it.
Can an object have more than one center of gravity?
No, objects cannot have more than one center of gravity. The center of gravity of an object can however change.
How does gravity keep objects in motion?
Gravity is a force that pulls objects towards each other. When an object is in motion, gravity acts as a constant force that keeps pulling it back towards the center of mass of the larger object, such as the Earth. This continuous pull of gravity helps to maintain the object's motion in its orbit or trajectory.
Why does the center of gravity and center of buoyancy always not in same position?
Center of gravity is supposed to act at the centroid of the body. while center of buoyancy is the center of gravity of fluid displaced . so they cant be at single point. if the body is completely submerged and homogenous then both cg and cb will coincide
Is it possible for an object not to have a center of gravity?
No, but the centre of gravity need not be inside the object. Not unless Gravity is not a variable. But it is not possible for an object to not have a center of mass.
