Summary of Newton`s Laws
... When you sit in your chair, your body exerts a downward force on the chair and the chair exerts an upward force on your body. There are two forces resulting from this interaction - a force on the chair and a force on your body. These two forces are called action and reaction forces and are the subje ...

Newton’s Laws of Motion
... less mass, the object with less mass will accelerate more quickly. Everyone unconsciously knows the Second Law- We already know that heavier objects require more force to move the same distance as lighter objects. Example: How can you increase the acceleration of the wagon? One way is to increase ...
