Newton’s By Brent Caldwell nd 2 Law Newton’s second law explains how an object will change its velocity if it is pushed or pulled on Force = Mass x Acceleration The SI unit for force is the Newton One Newton is equal to 0.225 lbs. One pound is equal to 4.448 Newtons If you push an empty cart with the same force you would use to push a full cart, the empty one will have a much greater acceleration If you push an empty cart with the same force you would use to push a full cart, the empty one will have a much greater acceleration If masses are the same, the greater force produces a high acceleration The acceleration of an object is proportional to the net force on the object and inversely proportional to the object’s mass An unbalanced force acting on an object causes it to accelerate The acceleration of an object is directly proportional to the net force and inversely proportional to it’s mass Acceleration is inversely related to the mass of the object Ex. - Large Mass = Small Acceleration Ex. - Small Mass = Large Acceleration Source Page Info from slides 5 and 6 http://www.wisconline.com/objects/ViewObject.aspx?ID= TP1302 Picture http://www.celsum.com/Graphics/newton _cradle.gif
