Newton's laws
of motion
Newton's first law
This law sates that an object will remain at rest or move in a straight line with constant speed unless it is acted upon by another force. An example of this would be a ball rolling on the ground, it would keep going but because of friction it will stop. See picture of boy throwing ball above.

Newton's second law
The second law states that an object acted on by an unbalanced force will accelerate in the direction of the force. An example of this would be a soccer player kicking a soccer ball, the soccer ball will go in the direction of the force, the soccer player acts as the ubalanced force and is acting upon the soccer ball which makes it move. See picture of boy kicking a soccer ball above. Source: http://teachertech.rice.edu/Participants/louviere/Newton/law2.html
Newton
Newtons third law states that for every force there is a reaction force that is equal in size, but opposite in direction. an example of this would be when a rocket takes off its action is to push down on the ground with the force of its engines, and the reaction is that the ground pushes pushes the rocket upwards with an equal force. see picture of rocket above.
