Study Notes
Newton's First Law
- Also known as the Law of Inertia.
- Describes that an object in motion will stay in motion at a constant velocity unless acted upon by an external force.
- An object at rest will remain at rest unless acted upon by a force.
Key Concepts
- Inertia is the property of matter that causes it to resist changes in its state of motion.
- This law demonstrates the relationship between force, mass, and motion.
Practical Applications
- A hockey puck sliding on ice will continue to move until friction or another force stops it.
- A passenger in a car lurches forward when the car suddenly stops due to their inertia.
Terms to Remember
- Inertia: Resistance of any physical object to any change in its velocity.
- Force: Any interaction that, when unopposed, will change the motion of an object.
Summary
- Newton's First Law emphasizes that forces are necessary to change the state of motion of objects.

Description
Test your knowledge of Newton's first law with this quiz. Also known as the law of inertia, this fundamental principle states that an object in motion will stay in motion, and an object at rest will stay at rest, unless acted upon by an external force. See how much you know about inertia and the behavior of objects in motion!
