To find force we multiple and . I also learned that Newton's Third Law states that for every there is an equal and . is the amount of matter in a body . Mass is always constant . I also learned that and are not the same . is the force of gravity acting on a body . This is why astronauts experience in space . is the force which opposes motion . There are useful examples of friction such as in car . However , if we want to reduce friction we use a technique called . I also learned a key relationship between the force applied to an elastic object and the of this object . This is also known as Law . Finally I learned that is done when a moves an object over a certain .
