How do we know that a fluid exerts an upward force on an object submerged in the fluid?
When an object is submerged in a fluid, the fluid exerts an upward force on the object due to the pressure difference between the top and bottom of the object. This upward force is known as buoyant force and is equal to the weight of the fluid displaced by the object. This is known as Archimedes' principle, which states that the buoyant force is equal to the weight of the fluid displaced by the object.
When one force acts a second force is produced that is and opposite to the original force.?
This is known as Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. When one object exerts a force on another object, the second object exerts a force of the same magnitude but in the opposite direction.
When action reaction force pairs come into being the action force is created first?
In every action-reaction force pair, the action force and the reaction force are created simultaneously. When one object exerts a force on another object, the second object exerts an equal and opposite force back on the first object at the same time. This is known as Newton's third law of motion.
What force opposes the downward motion of falling object?
The force that opposes the downward motion of a falling object is air resistance, also known as drag force. This force acts in the opposite direction to the motion of the object and increases with the speed of the object.
What is the force of every object universe exerts on every other object?
This force is known as gravitational force and is determined by the masses of the objects and the distance between them. It follows Newton's law of universal gravitation.
What force is a push or pull on an object by another object?
That force is known as contact force, which occurs when two objects are touching each other and one object exerts a force on the other. Contact forces include friction, normal force, tension, and applied force.
What force is acted on by another?
The force that is acted upon by another force is known as the reaction force. According to Newton's third law of motion, "For every action, there is an equal and opposite reaction." This means that whenever one object exerts a force on another object, the second object exerts an equal and opposite force back on the first object.
When one object exerts a force on a second object the second object exerts an equal and opposite force on the first object?
This concept is known as Newton's third law of motion. It states that for every action, there is an equal and opposite reaction. In other words, when object A applies a force on object B, object B applies an equal force in the opposite direction on object A.
The gratest velocity a falling objects reaches?
The greatest speed a falling object is known as its terminal velocity. At this speed, the drag force from the air is equal to the object's weight, and so there is no net force to accelerate the object further.
When the only force acting on a falling object is gravity?
This is commonly known as Free Fall
What Force That Gravity exerts on a mass?
The force that gravity exerts on a mass is known as weight. Weight is the gravitational force acting on an object due to the mass of the object and the acceleration due to gravity. It is calculated using the formula: weight = mass x gravity.
Why water produces upthrust?
Water produces upthrust, also known as buoyant force, due to its density and the pressure it exerts on objects submerged in it. When an object is placed in water, the surrounding water exerts an upward force on the object because the pressure at the bottom of the object is greater than at the top, resulting in buoyancy.
