If an object is in static equilibrium (or "stable"), there is no net force acting on the object.
When the only force on an object is the force of gravity,we say that the object is in "free fall".
The buoyant force acting on an object floating in a fluid is equal to the weight of the fluid displaced by the object. This force is responsible for keeping the object afloat and is determined by the density of the fluid and the volume of the submerged part of the object. Objects will float when the buoyant force is greater than or equal to the weight of the object.
Speeding object can still exhibit force, known as kinetic force, due to its movement. However, in a non-contact situation like saying an object is speeding, we don't usually refer to the force it carries in that context. Force is typically associated with interactions between objects.
When the only force on an object is the force of gravity,we say that the object is in "free fall".
The type of force that keeps an object such as the Earth moving in a circle is a combination of gravity and centrifugal force. Gravity wants to pull the object inward, but centrifugal force wants to push the object outward. This combination keeps objects going in a circular path. You could also say that, for objects such as a rock attached to a rope that is swung in circles, the forces are the tension of the rope opposing centrifugal force. This is essentially the same thing, except with different forces at work.
when a force acts to move an object,we say that work was done on the object
To find the force on an object, you multiple the mass of the object by its accelerationFor example, let's say a ball is moving at 7 m/s squared and has a mass of12 kg.The formula for force is: F = maF = 12 kg x 7 m/s squaredF = 84 N ( the unit for force is N, which is Newtons)*Be careful, an object does not "have a force". A force is an action that can modify the shape of an object and/or modify its velocity. Therefore, you do not calculate the force of an object, but the force required to give it a certain acceleration.
If an object is moving with constant velocity, then the net force acting on it is zero. This means that the forces acting on the object are balanced, resulting in no acceleration and a constant velocity.
Gravity is a force that attracts objects towards the center of the Earth, and its strength is determined by the mass of the objects involved. Upthrust, also known as buoyancy, is the force exerted by a fluid that opposes the weight of an immersed object. The size of gravity is typically larger than the size of upthrust, as gravity is a fundamental force that affects all objects, while upthrust depends on the density of the fluid and the volume of the object.
When an object accelerates, the force is unbalanced.
Work is done on an object when a force is applied to the object and the object moves in the direction of the force. The work done is calculated as the product of the force applied and the distance the object moves in the direction of the force.
There are many forces acting on a body. But, the moves because of the net force acting on it. So, we can say that the body accelerates because of net force acting on it only.
