Solution:

#### 1. Strength or energy as an attribute of physical action or movement.
- Definition: This refers to the ability to cause a change in motion or deformation.
- Match: G. Force

#### 2. A coherent typically large body of matter with no definite shape.
- Definition: This describes a state of matter that can flow and take the shape of its container but has a fixed volume.
- Match: O. Mass

#### 3. A unit of a system of units used for expressing how much an object matters weights.
- Definition: This is the measure of the gravitational force acting on an object.
- Match: P. Weight

#### 4. The force that attracts a body toward the center of the Earth.
- Definition: This is the fundamental force responsible for pulling objects toward the Earth.
- Match: E. Gravity

#### 5. The universe using a force that is directly proportional to the product of their masses.
- Definition: This describes the universal law governing the gravitational attraction between two masses.
- Match: C. Law of Universal Gravitation

#### 6. An object at rest stays at rest and an object in motion stays in motion.
- Definition: This is Newton's first law of motion, also known as the law of inertia.
- Match: N. Newton's 1st Law of Motion

#### 7. A net force is directly proportional to the magnitude of the net force.
- Definition: This is part of Newton's second law, which relates force, mass, and acceleration.
- Match: H. Newton's 2nd Law of Motion

#### 8. For every action, there is an equal and opposite reaction.
- Definition: This is Newton's third law of motion, describing the interaction of forces.
- Match: L. Newton's 3rd Law of Motion

#### 9. A tendency to do nothing or to remain unchanged.
- Definition: This is the property of an object to resist changes in its state of motion.
- Match: M. Inertia

#### 10. The resistance that one surface of an object encounters when moving over another.
- Definition: This is the general term for the force opposing motion between surfaces.
- Match: D. Friction

#### 11. Is the friction that exists between a stationary object and the surface on which it's resting.
- Definition: This is the type of friction that prevents an object from starting to move.
- Match: A. Static Friction

#### 12. A type of friction motion between two surfaces in contact.
- Definition: This is the friction that occurs when an object slides over a surface.
- Match: K. Sliding Friction

#### 13. Is the force resisting the motion when a body (such as a ball and wheel) rolls.
- Definition: This is the friction specific to rolling motion.
- Match: B. Rolling Friction

#### 14. Is a force that is caused by air.
- Definition: This is the resistance experienced by an object moving through air.
- Match: J. Air Resistance

#### 15. Is defined as the sum of all the forces acting on an object.
- Definition: This is the total force acting on an object, considering all individual forces.
- Match: F. Net Force

#### 16. The velocity at which a falling object moves through a medium as air.
- Definition: This is the constant velocity reached when the force of gravity equals the force of air resistance.
- Match: I. Terminal Velocity
