2.6.D—Describe inertial and gravitational mass

Describe inertial and gravitational mass.

• Objects have inertial mass, or inertia, a property that determines how much an object’s motion resists changes when interacting with another object.
• Gravitational mass is related to the force of attraction between two systems with mass.
• Inertial mass and gravitational mass have been experimentally verified to be equivalent.
