Newton's First Law of Motion: Inertia
An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Any object in motion will stay in that motion until a stronger force acts upon it. Any object at rest will stay at rest until any unbalanced or stronger force comes along to move it .
Example: The biker was riding and hit something causing him to come to a quick stop making him flip.
In demo: A skate board is rolled and keeps on rolling until it hits a wall.
Newton's Second Law of Motion: Acceleration
Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).
When something's velocity speeds up the rate depending on the mass of the object.
Example: The red line is the greater mass that speeds up a lot slower than the blue lie which is the object which has a lot less mass.
In demo: A large textbook is being pushed at the same time a small ball is also being pushed.
Newton's Third Law of Motion: Action and Reaction
For every action there is an equal and opposite re-action.
This law is basically saying to put it in laymen's terms that every time force is applied between two or more objects there will be a opposite reaction.
Example:The man is having to pull harder but flies away because of the force of the tree.
In demo.:A book and ball hit causing the ball to fly back.
