What is the weakest of the four fundamental forces?

What is the weakest of the four fundamental forces?

Actually, gravity is the weakest of the four fundamental forces. Ordered from strongest to weakest, the forces are 1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravity. Because they both have mass, the two protons exert gravitational attraction on each other.

Which is the strongest fundamental force?

strong nuclear force

What is value of g’on Earth?

9.80665 m/s2

What is the normal reaction?

A force acting perpendicular to two surfaces in contact with each other. If weight is the only vertical force acting on an object lying or moving on a horizontal surface, the normal reaction force is equal in magnitude, but opposite in direction to the weight.

What is the weight in physics?

Weight is a force acting on that matter . In physics, the term weight has a specific meaning – which is the force that acts on a mass due to gravity. Weight is measured in newtons. Mass is measured in kilograms. The mass of a given object is the same everywhere, but its weight can change.

Why is the weight negative?

So say there is some weight of an object, and the object’s mass is multiplied by the acceleration due to gravity pointing downwards, so the weight becomes negative when the positive mass is multiplied by a negative acceleration.

Can anything mass negative?

Hypothetically, matter can have negative mass in the same sense that an electric charge can be either negative or positive.

What does a negative weight mean?

It is a weighted graph in which the total weight of an edge is negative. If a graph has a negative edge, then it produces a chain. After executing the chain if the output is negative then it will give – ∞ weight and condition get discarded.

Can you have negative density?

Same goes for volume charge density. Like any density, charge density can depend on position, but charge and thus charge density can be negative. The term negative charge density is incorrect. Consequently, there can be a density of negative charge but can not be negative charge density.
