Law number one, an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an external force (physicsclassroom.com). It is basically saying that if you are not moving then you don't leave the spot you are situated at. And if you are moving at the same speed and going in the same direction then you stay in a constant motion. So basically it's like standing at the crosswalk, waiting for the pedestrian light to say go. You stay at the curb waiting for the light so you are technically at rest. When the light says go you are moving at a constant speed till you reach the other side which is in the same direction with no change, so you are now in motion.
Here is a animation of rest and motion.
Law number two, the acceleration of an object is dependent upon two variables, the net force acting upon the object and the mass of the object (physicsclassroom.com). Basically the acceleration of an object depends on: the net force which is the overall force or the sum of all forces acting on the object which is directly dependent, and the mass of the object which is inversely dependent. The overall force is like a basketball game, a successful play is dependent on your teammates, the other team and their plays. These together are like the overall force on an object. For mass, I think you guys get that, though mass is not weight it is still a measurement of something.

Law number three; for every action, there is an equal and opposite attraction (physicsclassroom.com). In translation, this means that forces come in pairs, that the size of the forces on the first object is the same size of the force for the second object, and that the direction of the force on the first object is the opposite direction of the second object. Like how everything comes in pairs, table items come in pairs like salt and pepper, sugar and cream, and ketchup and mustard. The opposite tastes are what make the taste buds neutralize... IDK....
Here is a animation of pairs, remember Mr. Salt and Mr. Pepper? Lol, well, yeah. :D
It's easy to understand how you explain the laws! Haha I like your examples! :]
ReplyDeletethanks it was so confusing at first so i tried to break it down as best as i could.
ReplyDeleteWoah, nice animations it really adds to your detailed explanation of the three laws.
ReplyDeletethanks, blake. i was too lazy to take out my pen and pad so i just did everything on the computers
ReplyDeletefor the second law your picture reminded me of air hockey &i realized thats kind of a good example of the second and third laws. Too bad i didnt think of it until now :p
ReplyDeletebut i like how you made the team a component of the laws.
merci, kim. don't worry i'm not going to go all français on you. yeah, i tried to think of something that represented forces and i thought of basketball (lots of pressure and forces coming at you when you are the midget of the team).
