The normal force is what prevents an object from falling through the ground.
The force of gravity is equal to the product of the mass and acceleration due to gravity, so the ground that the object sits on must apply an equal force in the opposite direction (Newton's Third Law), other wise the object would fall through.

What is the force of gravity in the surface of Mars?
Mars has a force of gravity equal to 3.7m/s2.
Is mass x gravity equal to an objects acceleration?
Well, first let's look at what gravity is. If we consider "gravity" as gravitational force, then force=mass x acceleration, and mass x gravity does NOT equal acceleration. Acceleration is the change of velocity, so an object could accelerate without being affected by gravity, maybe just another force, like jet engines or something. Basically, no.
What is the gravity at the surface of Mars?
The force of gravity on Mars is equal to 3.7m/s2. Mars's force of gravity is therefore 37.8% that of Earth's.
What is 90 percent of Earths gravity?
8,9 m/s2 The gravitational attraction on the surface of Venus.
What would happen to an object when normal force and force of gravity is applied?
When a normal force and force of gravity act on an object, the object will either remain stationary if the forces are balanced, or accelerate in the direction of the unbalanced force if there is a net force acting on it. The normal force is perpendicular to the surface the object is in contact with, while the force of gravity acts vertically downward towards the center of the Earth.
What is the product of mass and force due to gravity?
The product of (mass) x (force) has no physical significance.The product of (mass) x (acceleration due to gravity) is the force due to gravity,which we usually call "weight".
What is the equal and opposite force to the downward force of gravity pulling on a man standing on the beach?
The equal and opposite force to the downward force of gravity pulling on a man standing on the beach is the normal force exerted by the ground pushing back up on the man. This normal force prevents the man from sinking into the ground due to the force of gravity.
What are the 2 forces that are not equal in size?
Gravity and the normal force exerted by a surface are two forces that are not always equal in size. Gravity pulls objects downward, while the normal force pushes back upward on an object to prevent it from sinking into a surface.
If you stand on the ground with the action force of gravity pulling down in which direction is there a reaction force?
The reaction force to gravity is the ground pushing back up against you with an equal force to support your weight. This is known as the normal force.
If a Normal Force (Fn) is equal and opposite to gravity then why do objects fall?
Objects fall due to the force of gravity overpowering the normal force acting on them. Gravity pulls objects downwards towards the center of the Earth, causing them to accelerate towards the ground despite the presence of the normal force pushing back upwards. Once the force of gravity exceeds the normal force, the object will fall.
What is normal force?
Normal force is the force of a surface acting on an object( the normal force is perpendicular to the plane of contact). This force is directly related to the force of gravity, as the third law of newton state that when a force is applied to an object it will react with an equal force in the opposite direction. So when an object is placed on a surface, the force of gravity is acting on it (pulling it down), but the is object remain in place due to the normal force (which is pulling up on the object). In addition, a change to the force of gravity will result in the same change to the force of normal, to allow an object to remain stationary.
How do you measure friction when not knowing the normal force?
Well you can always work out the normal force... if the object is on a horizontal surface... The normal force is equal to the mass of the object × gravity (9.81). If the object is on an incline, you have to get the component of weight which is equivalent to the Normal, in most cases it is Normal = mass × gravity × cos(theta), theta being the angle of inclination.
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 exert a force equal to that of the force exerted on the desk from gravity. This force is called a "normal force"
What force is exerted toward you when you sit in a chair?
When you sit in a chair, the force exerted toward you is the normal force, which is equal in magnitude and opposite in direction to your weight. This force is what keeps you from falling through the chair due to gravity.
What is the coefficient of kinetic friction between a 400kg safe and the the floor when 760N are applied to the right?
The coefficient of kinetic friction can be calculated by dividing the force of friction (760 N) by the normal force between the safe and the floor. The normal force is equal to the weight of the safe, which is the product of the mass (400 kg) and the acceleration due to gravity (9.8 m/s^2). After finding the normal force, you can calculate the coefficient of kinetic friction by dividing the force of friction by the normal force.
