Newton's First Law of Inertia

• He studied the forces and how they affect an object’s motion.

  ​

• He formulated the three laws of motion​

Isaac Newton

Objects do not move or change their motion unless forced to do so. This resistance to a change in motion is called inertia.

​

It is also known as Newton’s first law of motion.

​Can objects move without a force?

​

An object at rest stays at rest unless acted upon by an unbalanced force.​

First Law of Motion

An object in motion will remain in motion unless acted on by an unbalanced force.
