Newton's First Law of Motion, also known as the Law of Inertia, states that an object at rest will remain at rest unless acted upon by an unbalanced force.
Inertia is the property of an object that resists changes to its state of motion.
Newton's First Law of Motion states that an object in motion will remain in motion unless acted upon by an unbalanced force.
The greater the mass of an object, the greater its inertia.
True
Match the example with its description under Newton's First Law:
Car Starting ↔️ Engine acceleration causes motion
Book on a Table ↔️ Gravity keeps the book at rest
Puck Sliding on Ice ↔️ Friction slows the puck
Match the quantity with its correct unit:

Mass ↔️ Kilograms (kg)
Acceleration ↔️ m/s²
What is the unit of acceleration?
m/s²
The greater the force applied to an object, the greater its acceleration.
True
