Study Notes
Inertia and Mass
- The Law of Inertia states that an object at rest will remain at rest, and an object in motion will continue to move with a constant velocity, unless acted upon by an external force.
- The measure of the amount of matter in an object is defined as its mass.
- Mass is a measure of an object's inertia, with more massive objects having a greater tendency to resist changes in their motion.
Force and Inertia
- According to the Law of Inertia, an external force is required to change the motion of an object.
- The role of force is to overcome an object's inertia, either to cause it to accelerate, decelerate, or change direction.
- The more massive an object, the greater the force required to change its motion.
Key Points
- Inertia is the tendency of an object to resist changes in its motion.
- The Law of Inertia applies to both objects at rest and objects in motion.
