One newton (N) of force is enough to accelerate 1 kilogram (kg) of mass at a rate of 1 meter per second squared (m/s2). In fact, this is really how force and mass are defined. A kilogram is the amount of mass which 1 N of force will accelerate at a rate of 1 m/s2. In ...
What Is A Force? Force A force can be apush or a pull. A force acting on a body tend to produce a change invelocityoraccelerationof the body. SI unitof force is thenewton (N). It is avector quantity. We can add/subtract forces. (More about this atAddition of forces)...
Newton's theory says this can occur because of gravity, a force attracting those objects to one another or to a single, third object. Einstein also says this occurs due to gravity — but in his theory, gravity is not a force. It's a curve in space-time. According to Einstein, those...
