What is the force exerted by the load being lifted called?
The force exerted by the load being lifted is called the weight of the load. It is the force acting downwards due to gravity. This weight needs to be overcome by the lifting force to lift the load.
Why does an object in orbit needs a centripetal force act?
An object in orbit needs a centripetal force to keep it moving in a circular path. Gravity provides this centripetal force, pulling the object towards the center of the orbit. Without this force, the object would continue in a straight line tangent to the orbit.
What does an object need in order to have gravity?
There is a force of gravity between every pair of masses. So any object with mass is attracted to every other object with mass.
What is needed to make an object accelerate?
To make an object accelerate, a force needs to be applied to the object. This force can come from various sources such as gravity, friction, or propulsion. The magnitude and direction of the force will determine the rate at which the object accelerates.
What is needed for an object to move?
For an object to move, it needs a force to act upon it. This force can be exerted through actions like pushing, pulling, or gravity. Additionally, the object must be free to move, with no constraints holding it in place.

Why does more weight needs more force?
More weight requires more force to overcome the force of gravity acting on the object. The force of gravity is directly proportional to an object's mass, meaning heavier objects experience a greater gravitational force pulling them downward. To lift or move heavier objects, more force must be applied to counteract this gravitational force.
What is needed to make something move?
To make something move, a force needs to be applied to the object. This force can come from various sources such as pushing, pulling, gravity, or a motor. The object will then accelerate in the direction of the force applied.
How do you calculate upward force to keep an object in the air?
Basically, the upward force has to counteract the downward force of gravity. Thus, the upward force has to be equal to the object's weight. There is not much calculation to do here; just use the standard formula for weight: weight = mass x gravity Under normal Earth gravity, you can use 9.8 for gravity; thus, every kilogram has a weight of about 9.8 newton, and therefore requires an upward force of 9.8 newtons to keep it in balance.
What is the difference between thrust upthrust weight and gravity?
Thrust is the amount of force exerted by an engine on the object resulting in acceleration. force = mass * acceleration directing thrust in a direction so the object travels upward or directly opposing gravity is upthrust. weight is how much an object with mass feels gravity a mass of x on earth will feel y newtons of force that is y=x*9.8 where 9.8m/s is the gravity of earth. the same object on the moon still has x mass but now only produces Y=x*1.62 of downward force so to lift an object off the ground one needs upthrust=mass of object * gravity + acceleration of motion for movement
If matter moves a force acted on it?
Matter is held down by the force of gravity, like a cup placed on a tabletop. The cup needs either for the table to be tilted, allowing gravity to cause the cup to overcome the force of friction and to slide off the table, or someone needs to push (force) the cup sideways.
The force of gravity on a 4kg object is twice that on a 2kg object Why does the 4kg object not fall with twice the accleration?
The reason that a heavier object does not fall faster even though there is more gravitational force on it is because it has more mass, and more energy is required to accelerate the greater mass. A small mass doesn't need a lot of force on it to accelerate it. It's "light" in weight. But a heavier one needs more force on it to accelerate it equally. Want a heavier object to accelerate the same as a lighter one? Apply more force. Gravity does that. Automatically. Think it through and it will lock in.
How much force does it take to break away from earths gravity?
To break away from Earth's gravity and reach space, an object needs to reach an escape velocity of about 11.2 kilometers per second (about 25,000 mph). The force required to achieve this velocity is enormous and depends on the mass of the object. For example, a spacecraft with humans onboard would need powerful rockets to generate enough force to break free from Earth's gravity.
