Newton's first law is a special case of the second law when the net force on an object is zero. Newton's second law applies to macroscopic objects moving much slower than the speed of light. • Sections: • 00:00 - Intro • 00:23 - Connecting acceleration and net force • 04:59 - Effect of mass on acceleration • 06:13 - Newton's second law • 07:08 - Newton's first law is a special case of the second law • 07:50 - Inertia and mass • 08:30 - Limitations of Newton's law • 09:05 - Applying Newton's second law • ------------------ • Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere.
