The four forces are: strong nuclear force, weak nuclear force, electromagnetic force, and gravitational force.
Both the strong nuclear force and the weak nuclear force have a very limited range, although very strong compared to the other two forces neither can reach outside the atomic nucleus.
The electromagnetic force has an infinite range and can in principle act between all objects all the time, but the fact that it comes in opposite polarities (i.e. plus/minus electric charges, north/south magnetic poles) that attract and cancel each other, most objects have no net electromagnetic field and thus cannot act on any other object.
The gravitational force has an infinite range and only one polarity (i.e. attractive), so although it is the weakest of all the four forces, it alone can act between all objects all the time.
What else can I help you with?
What is one force that acts on all objects on earth including humans all the time?
Gravity is a force that acts on all objects on Earth, including humans, all the time. It pulls objects towards the center of the Earth and gives weight to objects.
How do you calculate gravity from distance and time?
The force of gravity between two objects can be calculated using Newton's law of universal gravitation: F = (G * m1 * m2) / r^2, where F is the force of gravity, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between the centers of the two objects. Time does not directly affect the calculation of gravity, as gravity is a force that acts instantaneously between objects.
How does the gravitational force between two objects that are close together compared to the gravitational force between two objects as they move farther apart?
As the objects move farther apart, the gravitational force between them decreases. Every time the distance between them doubles, the force between them drops 75%.
How does gravitational force between two objects that are close together compared to the gravitational force between two objects as they move farther apart?
As the objects move farther apart, the gravitational force between them decreases. Every time the distance between them doubles, the force between them drops 75%.
How does the gravitational force between two objects that are close together compare to the gravitational force between two objects as they move farther apart?
The gravitational force between two objects decreases as they move farther apart. This decrease is described by the inverse square law, which states that the force is inversely proportional to the square of the distance between the objects. So, as the distance between the objects increases, the gravitational force weakens.
Impulse is the product of force and the what During which that force acts?
time
Distinguish between impact and impulse Which designates force and which is force multiplied by time?
In physics, impulse is force multiplied by time. It's important for things like rockets. Impact has no equivalent physical meaning. It is a word in the English language that has a number of meanings, but principally connotes a collision between at least two objects.
Why isn't time a variable that affects the amount of gravitational force between two objects in space?
To calculate the gravitational force between two objects, all you need is the mass of those two objects, and the distance between their gravitational centers. If You know that, you can calculate the magnitude of the force, and it doesn´t matter if that situation occurs right now, in 2 days, or in 1357. If you want anything to change (force magnitude, distance or whatever you want), of course, you need time, but you cannot make any statements about a physical situation if you only know the time, or how much time has passed.
What is gavitational force?
gravitational force is a basic force of nature, it presents everywhere and at all time. The gravitational force acts between any 2 masses in the universe and pulls them toward each other .It is the force that pulls objects toward earth.
Is the product of a force and the time during which the force acts.?
Impulse - APEX ! =)
Do some forces act on objects?
No because friction will be different for different objects, so you have to take that into account. If you push something through water it will move a lot easier than if you apply the same force to a desk that is nailed to the floor :P
Impulse is the product of a force and the blank during which that force acts?
Impulse is the product of a force and the time interval during which that force acts. It represents the change in momentum of an object.
