is normal force the same as gravity?

The normal force on an object at rest on a flat surface is equal to the gravitational force on that object. In equation form, that means .

One g is the force per unit mass due to gravity at the Earth's surface and is the standard gravity (symbol: gn), defined as 9.80665 metres per second squared, or equivalently 9.80665 newtons of force per kilogram of mass.

Three similarities between electrostatic and gravitational forces are : Both of them are inverse square forces, i.e. they fall of as 1/r^2 where r is the distance between the two particles. Both of them are central forces, i.e. angular momentum conservation occurs. The forces are conservative.

Explanation: Normal force is defined as the force that a surface exerts on an object. If the object is at rest, net force on the object is equal to zero; therefore, the downward force (weight) must be equal to the upward force (normal force). Since weight acts in the downward direction it will be negative.

Gravity and Weight Weight is a measure of the force of gravity acting on an object. According to Newton's laws of motion, force is directly proportional to both mass and acceleration, and the equation for force is F = m * a, where m = mass and a = acceleration.

Acceleration can cause the feeling of gravity by pushing you toward the ground but it is not gravity. Actually acceleration and gravity is same, no difference. But acceleration is general term while gravity is specific term used for the gravitational acceleration of earth.

Gravity is a force which tries to pull two objects toward each other. Anything which has mass also has a gravitational pull. The more massive an object is, the stronger its gravitational pull is. Earth's gravity is what keeps you on the ground and what causes objects to fall.

Gravity is the main force responsible for mass movements. Gravity is a force that acts everywhere on the Earth's surface, pulling everything in a direction toward the center of the Earth. On a flat surface, parallel to the Earth's surface, the force of gravity acts downward.

Gravity is a fundamental underlying force in the universe. The amount of gravity that something possesses is proportional to its mass and distance between it and another object. This relationship was first published by Sir Issac Newton.

Gravitational force between two objects is given by F=G(m1)(m2)/(r^2). G is the universal gravitational constant with the value of 6.67*10^-11. m is the rest mass of a proton, at 1.67*10^-27 kg. Electrostatic force between two charges is given by F=(q1)(q2)/(4πεο r^2).

This law states that two objects attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. ... And while the force of gravity may feel like zero out in space, gravity is everywhere all the time.

If there is just one force on an object, then that force is the net force. ... For example in free fall, the net force on an object equals its weight - the one force pulling on it. If 2 forces push or pull on an object in opposite directions, and the two forces cancel each other exactly, the net force is zero.

Remember from working with forces that force is equal to the mass times acceleration. As we increase the force on an object the acceleration increases proportionally. Since the mass does not change as the acceleration increases, we can say that force is equal to acceleration.

The atmospheric pressure and gravity are very closely related. The force of gravity is acting on mass of gas particles in the atmosphere and pressing towards Earth's centre. ... So atmospheric pressure is due to gravity. Our weight is also due to gravity and always pressing downwards.

The gravitational force between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Mathematically, F = Gm1m1/r² Where, G is the universal gravitational constant, m1 and m1 are the masses separated by a distance r.

The normal force is the support force exerted upon an object that is in contact with another stable object. For example, if a book is resting upon a surface, then the surface is exerting an upward force upon the book in order to support the weight of the book.

“Lbf” refers to the gravitational force placed by a matter on the Earth's surface, while “lb” deals with the measurement of force. A pound force equals the product of 1 pound and the gravitational field. “Lb” and “lbf” are basically similar with each other since they both involve the same force.
