Force and Motion

What is a Field Force?

• A force that requires physical contact between objects.

• A non-contact force that is exerted between objects over a distance without any physical touching, such as gravity or magnetism.

• A force that only acts on objects in motion.

• A force that can only be observed in a laboratory setting.

System Noun

---

[sis-tuhm]

• The specific object or group of objects of interest that is being analyzed in a given physics problem or situation.

• A random collection of items without any specific focus.

• A method of solving equations in physics.

• A type of energy transformation.

Agent Noun

---

[ey-juhnt]

• The specific and identifiable source or cause that is responsible for exerting a particular force on a system or object.

• A person who is hired to perform a specific task or job.

• An object that is acted upon by a force.

• A concept that describes the relationship between two variables.

What is Gravitational Force?

• A fundamental, attractive field force that exists between any two objects that possess mass, pulling them toward each other.

• A repulsive force that acts between two objects with the same charge.

• A force that only acts on objects in motion, causing them to accelerate.

• A force that is only present in outer space, affecting celestial bodies.

What is the standard international (SI) unit of measurement for force?

• Joules (J)

• Newtons (N)

• Pascals (Pa)

• Watts (W)

What are vectors?

• Physical quantities that are fully described by having both a magnitude and a specific direction.

• Quantities that only have magnitude and no direction.

• A type of scalar quantity that represents size only.

• A mathematical concept that does not relate to physical forces.

Equilibrium

• The state of an object in which the net force acting on it is zero, resulting in no acceleration or change in velocity.

• A condition where an object is in constant motion without any forces acting on it.

• The point at which an object begins to accelerate due to an unbalanced force.

• A situation where two forces acting on an object are unequal, causing it to move.

Inertia

• The natural tendency of any physical object to resist changes in its state of motion.

• The force that causes an object to move in a circular path.

• The speed of an object in a straight line.

• The energy stored in an object due to its position.

What is a Free-Body Diagram?

• A diagram that shows the motion of an object over time.

• A simplified physical representation that illustrates all the individual forces acting upon an isolated system or object using vector arrows.

• A chart that lists all the forces acting on a system without any visual representation.

• A graphical representation of the energy transformations in a system.

What is the definition of Force?

• A push or a pull exerted on an object that has both magnitude and direction, causing a change in motion.

• A type of energy that can be converted into work.

• The mass of an object multiplied by its acceleration.

• A measure of the gravitational pull on an object.
