Define the following terms: Net Force

• The total force acting on an object, taking into account both magnitude and direction

• The force that opposes motion between two surfaces in contact

What is the term for the resistance of any physical object to any change in its motion?

• Inertia

• Momentum

• Force

• Acceleration

Friction is defined as:

• A force that opposes motion between two surfaces in contact

• A force that acts at a distance

• A force that causes objects to move

• A force that acts only in liquids

What is the definition of Air Resistance?

• The force that opposes the motion of an object through air

• The force that propels an object forward in air

• The energy required to lift an object into the air

• The speed at which an object falls through air

What does the Law of Universal Gravitation state?

• Every mass repels every other mass with a force proportional to their distances.
• Only large masses attract smaller masses with a constant force.
• Masses attract each other only if they are in contact.
• Every mass attracts every other mass with a force proportional to their masses and inversely proportional to the square of the distance between them.

What is the definition of Weight?

• The force exerted by gravity on an object

• The mass of an object

• The volume of an object

• The density of an object

Define the following terms: Law of Conservation of Momentum

• The total momentum of a closed system is constant unless acted upon by an external force.

• Energy cannot be created or destroyed, only transformed.

• For every action, there is an equal and opposite reaction.

• The acceleration of an object is directly proportional to the net force acting on it.
