When the only force on an object is the force of gravity,
we say that the object is in "free fall".
Potential energy.
it is free fall :)
Free Fall
balanced
An object at rest, or an object with a constant velocity are the two possible states of an object with zero net force. An object with zero acceleration has zero net force. There many be several forces acting on the object, such as the force of gravity and the normal force of the ground. Even though an object sitting on the ground has two forces acting on it (gravity, and the normal force) the object does not accelerate because these forces are equal and opposite. An object with zero net force has all forces acting on it equally balanced and cancelling out
the question is unclear
Newtons second law of motion
Objects can be made to float by reducing their overall density so that they become less dense than the fluid they are placed in. This can be done by using materials that are less dense than the fluid, such as foam or inflatable objects. Archimedes' principle states that the buoyant force acting on an object is equal to the weight of the fluid displaced by the object, so if the object weighs less than the fluid it displaces, it will float.

Newton's third law states: The mutual forces of action and reaction between two bodies are equal, opposite and collinear. in other words, gravity is an effect of 2 bodies acting on each other equally
no, but the force of gravity, also known as weight, does.
Archimedes Principle simply states that the buoyant force acting on an object equals the weight (force of gravity) of the fluid displaced by the object. He came to formulate it when he was in the tub, he noticed that before he got in, the water was at the rim and after he got in, the water had spilled over the top.

Newton's 2nd law of motion, F=ma, where Fand a are vectors.
Archimede's Principle states that the buoyant force that an object experiences when immersed in water is equal to the weight of the water displaced by the object.

The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.Since a bicycle has much less mass than a car so it's easier to push it.
By definition, every force acting on the object affects its velocity.Newton's second law states that the acceleration of an object (the rate of change of velocity with time) is equal to the net force on the object divided by the object's mass. Force is a vector, so if you have several forces acting on the object you must take their vector sum. Only if all the forces acting on the object sum up to zero will the object not accelerate. In that case it will remain stationary if it was already stationary, or continue to move in the same speed and in the same direction as before.
