Newtons first law states that "an object in motion will stay in motion and an object in rest will stay at rest."  If I were to drive a car and keep going in the same direction then I would stay in motion until some kind of force stopped me.  If I were to sit in a car and not do anything then i would be at rest until some kind of force moves me. 

 Newton second law states that "an object with an unbalanced force acting on it will move in the direction of that force."  If I was standing still, talking to someone and someone else was running and they didn't see me and ran into me, I would be forced forward.   

Newtons third law states that "forces occur in equal and opposite pairs."  If a rocket was going to take off into space the ignition from the rocket and the ground would cause it to go up.  The ground pushes the rocket up because of the ignition.   

 

Cheetahs are the fastest land animals in the world.  They are being protected by hunters and other people who want to hurt them.  Did you know that another name for the cheetah is the Acinonyx Jubatus. An adult body can be 105-152 cm long, the tail can be up to 51-87 cm and the shoulder height is 62-86 cm. The weight of the cheetah is 31-64kg. The male is slightly larger than the female but there both fast. If you try to run away from a cheetah you wouldnt even get 5ft before it cought you.  The cheetah can run a constant speed of 75mph, and the length of 112-120km/h.  They can run up to 125mph.  The only enem for the adult cheetah are the humans, and cubs have to watch out for lions, hyenas,eagles, and jackals.

speed: The distance an object travels in a unit a time.

average speed: found by dividing the total distance traveled by the total time taken.

Instantaneous speed: the speed of an object at one instant of time.

velocity: an object is the speed of the object and the direction of its motion.

law of conservation of momentum: the total momentum of a group of objects remains constant unless outside forces act on the group.

The laptop is one of the worlds greatest invention.  we use the computer to play games, research, and do whatever we need done.  There are some people who stay on computers because they think that they need it all the time.  If computers were to never be made again i think that some people would have a hard time doing the things they need to do, other than reading books.  the first laptop was created in April of 1976 and created by the company Xerox PARC.  This computer costed $50,000 when they first came out!  Just think now u wouldn't think anyone would ever use this type compared to the ones we gave now.  If apple and Sony and all those other companies keep making computers then who knows what they will come up with. I think the computers we have now are a lot better that what they had in the past.
