What force acts against gravity in water?
Buoyant force acts against gravity in water. This force is exerted by the water on an object that is submerged or floating in it and acts in the opposite direction to gravity. Bouyant force is what allows objects to float and feel lighter when in water.
What is the amount of force required to lift an object against the force of gravity equal to?
The acceleration due to gravity (9.8 meters/sec.^2) * mass of object.
What can a push or a pull against motion can do?
A push or pull against motion can slow down, stop, or change the direction of an object's motion, depending on the strength and direction of the force applied. This can be achieved through friction, gravity, or other external forces acting on the object.
When an object is partly or wholly immersed in a liquid it is buoyed up by?
the buoyant force, which is equal to the weight of the liquid displaced by the object. This force acts in the opposite direction to gravity, reducing the net force on the object and causing it to feel lighter.
Why it is taken as negative when an object is thrown upwards against gravitation?
When we throw the object upwards we consider that upward direction as positive. Therefore, the velocity in that direction is positive but the acceleration due to gravity is in the opposite direction and so it is considered negative. But when the ball comes down again after reaching a certain height the velocity is in opposite direction to the earlier one and so the velocity now is negative as a result the acceleration is again negative.

Why is there a difference between the weight of an object in the air and it's weight in water?
Because of buoyancy ; something that acts in the opposite direction to the force of gravity to make the object feel lighter.

What opposing forces act on an object falling freely through the atmosphere?
The forces that affect the rate of a falling object are Gravity and Air Resistance. Gravity affects the speed and the velocity of the object by speeding it up as it falls closer to the earth, and Air resistance works against the object pushing against it.
Why it is taken as negative when an object is thrown upwards against gravitation?
When we throw the object upwards we consider that upward direction as positive. Therefore, the velocity in that direction is positive but the acceleration due to gravity is in the opposite direction and so it is considered negative. But when the ball comes down again after reaching a certain height the velocity is in opposite direction to the earlier one and so the velocity now is negative as a result the acceleration is again negative.
The what of an object changes if the force of gravity changes?
The weight of the object would change if gravity changes. cw: Yes, if the FORCE of gravity changes, the FORCE of the object in the downward direction changes.
Why does an object seem lighter in the water than in air?
Water constantly pushes upwards against an object making it seem lighter.
What is the direction of the force of gravity?
The force of gravity acts towards the center of mass of the object in question.
Why does a heavy object feel lighter when under water?
A heavy object feels lighter in water because the upward buoyant force exerted by the water opposes the force of gravity acting on the object. This buoyant force counteracts the weight of the object, making it feel lighter.
What is the force that acts against gravity?
The force that acts against gravity is called the normal force. It is exerted by a surface supporting an object, pushing upwards to prevent the object from falling due to gravity.
