The law can also be used to determine the net force required to produce a certain acceleration for a known mass. Remember that the force term in Newton's second law refers to the net force on the object. Sections: 00:00 - Example 1 (acceleration of an elevator) 04:10 - Example 2 (applied force on a sled) ------------------ Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere.
