A Brief Overview of Newton’s Three Laws of Motion


University student Matthew “Matt” Kafker studies a variety of topics, including computer science, math, and literature. However, Matt Kafker is perhaps most interested in natural sciences and is majoring in physics.

In the physics of motion, Sir Isaac Newton’s three laws are:

- First: Objects in motion will stay in motion unless an external force is applied to them. Similarly, objects at rest will continue resting without the addition of an external force.

- Second: An object’s acceleration and force are directly related. For example, when more force is applied to an object, that object will move at a faster rate. At the same time, the mass of an object is inversely related to an object’s force and acceleration.

- Third: All forces exist in pairs that are equal and opposite to one another. An example of this law is seen when a person steps off a boat. The person moving toward the shore is exerting force on the boat. In response to this action, the boat moves away from the shore with the same amount of force that was applied to it.
