Laws Of Motion !
DEFINITION:"The law of inertia", This means that there is a natural tendency of objects to keep on doing what they're doing. All objects resist changes in their state of motion. In the absence of an unbalanced force, an object in motion will maintain this state of motion.
Own Definition:'' Meaning that the object doesn't stop, it just keep on going and it changes in one state of motion.
Demonstration: ''An ball just sitting there, it wouldn't nothing, but as u constantly put outside force to it, it will NEVER STOP !.
Definition: ''Increase in the rate or speed of something,the rate at which the velocity of an object changes over time. An object's acceleration is the net result of any and all forces acting on the object, as described by Newton's Second Law''.
Own Definition: ''Speed and rate at which an material has its difference over time.
Demonstration: ''As u can see in the picture below, u can see the blue thing reaction on his face to when he hits the bricks with his foot, and his force that he uses is going towards the brick wall.
Action and Reaction..
Definition:'' According to Newton's third law, for every action there is an equal (in size) and opposite (in direction) reaction force. Forces always come in pairs - known as "action-reaction force pairs."
Own Definition: ''The opposite in size and direction,Which are tow of the same pairs...Action-Reaction.
Demonstration: Action-tire pushes on road.Reaction-Road pushes on tire
Action-Rocket pushes on gas.Reaction-Gas pushes on rocket
Action-Earth pulls on ball.Reaction-Ball pulls on earth
