If no force, the planets would move in a straight line, not in a orbit around the sun.
Newtons Second Law was F=ma, means the force(F) acting on object is equal to mass(m) of object times it's acceleration(a).
It depends on the angle between the two forces. It can be anything from 1 newton (if they're acting in exactly opposite directions) to 7 newtons (if they're acting in exactly the same direction).
Weight in Newtons.
A force vector of -3 Newtons indicates that the force is acting in the opposite direction of the positive direction, with a magnitude of 3 Newtons.
98.07 newtons on earth.
The quantity that is measured in Newtons is force.
If we have a force acting on a body and we know what that force is, and we also know that the force is gravity, we can solve because we know the force gravity exerts on a mass. If we take the total force acting on the body and divide it by the force of gravity per one unit of mass, we can find the number of units of mass that cause gravity to act on the object. We have 1033 Newtons of force acting on the object. Gravity pulls down with a force of 9.8 Newtons on 1 kilogram of mass. Our 1033 Newtons divided by 9.8 Newtons per kilogram = 105.41 kilograms
The measure of a force acting on a body is the mass of the body multiplied by its acceleration in the direction of the applied force.
The net force acting on the object is 6 newtons to the left. This is calculated by subtracting the force pulling to the right (3N) from the force pulling to the left (9N).
Gravity, mainly. The Sun attracts the planets, and - to a lesser degree - the planets attract one another.
Take the sum of the forces on the object on the horizontal plane(x-direction) with the positive direction being to the right. The 80 newtons to the right is +80N and the 80 newtons acting to the left is -80N. Add them up, so 80N - 80N = 0 N. The total force acting on the object is 0.
Mass is the amount of matter in an object, while weight is the force of gravity acting on that object. Mass is measured in kilograms, while weight is measured in newtons.
