Newton's third law of motion states that: "For applied force (A), exists some force (B) of equal magnitude acting in the opposite direction of the force applied.".
The force of the weight (which is the mass of the table multiplied by gravity) [W=mg] pushing down on the floor is counterbalanced by an equal and opposite force of the floor pushing up on the table. This is why the table does not fall through the floor. The floor is able to provide this force without allowing the table to move through it because the bonds between its atoms are strong enough.

The floor must exert an equal and opposite force to the gravitational force acting on the table to prevent it from falling through. This force is known as the normal force, and it acts perpendicular to the surface of the floor to support the weight of the table.

What opposing forces act on an object falling freely through the atmosphere?
The main opposing forces acting on an object falling freely through the atmosphere are gravity, which is pulling the object downward, and air resistance, or drag, which is pushing against the object in the opposite direction. At higher speeds, air resistance becomes stronger, eventually balancing out the force of gravity and causing the object to reach a terminal velocity.
How do balanced and unbalanced forces relate to a parachute?
If the parachutist is just falling down vertically, he is falling because of the unbalance force. Gravity is pulling him down. Gravity is stronger than the air resistance that is "keeping him up". The two unbalanced forces: gravity & air resistance. Because they are imbalance, he is accelerating towards the Earth's surface at 9.8 meters per second.
What causes the moon to have lessof an impact on tides at neap tides?
The Sun's gravity. At neap tides - the moon is exactly opposite the Sun in relation to the Earth. This means it's 'pulling' against the gravity of the Sun.
What is the reaction force if Sun's gravity pulling on Earth is the action force?
The reaction force in this scenario is the Earth's gravity pulling on the Sun. According to Newton's third law of motion, for every action force, there is an equal and opposite reaction force.
What is the direction and magnitude of the net force acting on a rain drop falling down with constant speed?
The net force acting on a raindrop falling down with constant speed is zero. The force of gravity pulling the raindrop down is balanced by air resistance pushing back up, resulting in a net force of zero.
To stop a table falling through the floor in your classroom what must the floor do against the force of the gravity pulling th table down?
Push it up.
What forces will br acting on a egg and a container while it is falling?
While the egg is falling, the main forces acting on it are gravity pulling it downward and air resistance pushing against it in the opposite direction. For the container, the forces are similar, with gravity pulling it downward and air resistance pushing against it. Friction with the surrounding air will also play a role in affecting the motion of both the egg and the container.
What is it called when gravity and air resistance of a falling object are balanced?
When gravity and air resistance of a falling object are balanced, it is called terminal velocity. At this point, the object falls at a constant speed because the force of gravity pulling it down is equal to the force of air resistance pushing back against it.
How does force and gravity effect a falling object?
As an object falls, gravity acts as an external force pulling it downward. This force causes the object to accelerate as it falls towards the Earth's surface. The object's speed increases until it reaches terminal velocity, when the gravitational force pulling it down is balanced by the air resistance pushing against it.
The forces acting on a falling leaf are?
The forces acting on a falling leaf are gravity pulling it downward and air resistance pushing against it as it falls. These forces determine the leaf's speed and trajectory as it descends towards the ground.
What force or forces are acting on the falling climber in picture?
The main forces acting on the falling climber are gravity pulling them downwards and air resistance pushing against their motion. These forces together determine the acceleration of the climber as they fall.
To stop the table in your class falling through the floor what must the floor do against the force of gravity pulling the table down?
The floor must provide an equal and opposite force to counteract the force of gravity pulling the table down. This support force from the floor prevents the table from falling through it.
When the only force affecting an objects is gravity that objects is in?
Freefall this means the objects is falling through the air while gravity is pulling.
What is the name for the highest speed when falling?
The highest speed when falling is called terminal velocity. This occurs when the force of gravity pulling an object down is balanced by the force of air resistance pushing against it, resulting in a constant speed.
What are the directons in which the forces are acting when a parachutist when he is falling?
When a parachutist is falling, the forces acting on them are gravity pulling them downward and air resistance pushing against their fall. Gravity is the dominant force causing the parachutist to accelerate towards the ground while air resistance counteracts this force, eventually leading to a terminal velocity where the forces are balanced.
When the only force affecting an object is gravity that object is in?
Freefall this means the objects is falling through the air while gravity is pulling.
What opposing forces act on an object falling freely through the atmosphere?
The main opposing forces acting on an object falling freely through the atmosphere are gravity, which is pulling the object downward, and air resistance, or drag, which is pushing against the object in the opposite direction. At higher speeds, air resistance becomes stronger, eventually balancing out the force of gravity and causing the object to reach a terminal velocity.
