Inertia- The Law of Inertia
Inertia is the property of matter that causes it to resist changes in motion, inertia is directly proportional to the mass of the object. So in other words, the more mass an object has, the more inertia. Newton's first law, also known as the law of inertia, states that an object will remain at rest or continue to move at constant velocity when the net force on the object is zero. However, there are some important implications to this first law; a non zero net force will change the velocity of an object, a net force is not required to maintain the velocity of an object, and external forces are required to change the motion of an object. Check out the video below for some examples of inertia!
