Balanced forces are responsible for unchanging motion. Balanced forces are forces where the effect of one force is cancelled out by another. A tug of war, where each team is pulling equally on the ...

Longer reaction times increase the thinking distance when stopping from a given speed. There are different ways to measure reaction times. One simple method involves dropping a ruler between ...

Your everyday notion of forces probably includes pushing and pulling and similar actions. Technically, when something is pushed or pulled we say that "a force is applied to the object". What happens ...

For the motion was only determined by the equation of motion if the force was given. Newton had the idea, to which he was probably led by the laws of the planetary motions, that the force acting ...

They talked of many things before the astronomer revealed his reason for seeking Newton out. What kind of curve, Halley finally asked, "would be described by the planets supposing the force of ...
