Newton's Third Law of Motion

What is the definition of Work?

• The transfer of energy that occurs when a force is applied to an object, causing it to move.

• The ability to do something or act in a particular way.

• A measure of the amount of matter in an object.

• The rate at which work is done.

Inertia

• An object's resistance to any change in its state of motion, which is directly related to its mass.

• The force that causes an object to accelerate when a net force is applied.

• The tendency of an object to remain at rest or in uniform motion unless acted upon by an external force.

• The measure of how much matter is in an object.

State of Motion

• The condition of an object's movement, describing if it is motionless, at constant speed, or accelerating.

• A term used to describe the speed of light in a vacuum.

• The force applied to an object to change its direction.

• The distance traveled by an object in a straight line.

What does the Law of Universal Gravitation describe?

• The gravitational attraction between any two objects that possess mass.

• The speed of light in a vacuum.

• The force of friction between two surfaces.

• The behavior of gases under pressure.

What is the definition of Mass?

• The amount of matter contained within a physical object, typically measured in units of kilograms (kg).

• The force exerted by gravity on an object.

• The volume of an object measured in liters.

• The density of an object calculated by its mass and volume.

What is Net Force?

• The total force acting on an object, combining all individual forces.

• The force exerted by gravity on an object.

• The force that opposes motion between two surfaces in contact.

• The force applied by a person to lift an object.

What are Balanced Forces?

• Forces that are equal in size and opposite in direction, resulting in a net force of zero.

• Forces that are unequal in size and direction, resulting in a net force greater than zero.

• Forces that act in the same direction, increasing the overall force applied.

• Forces that are completely unrelated and do not affect each other.

What is a Reaction Force?

• The force exerted by a second object back on the first, equal and opposite to the action force.

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

• The force that opposes the motion of an object in a fluid.

• The force that acts on an object due to gravity.

What is a Simple Machine?

• A complex device that requires multiple parts to function.

• A basic mechanical device that makes work easier by changing a force's direction or its magnitude.

• A type of machine that can only move in one direction.

• A device that generates electricity from mechanical energy.

What is the definition of Motion?

• The action or process of an object changing its position or location over a period of time.

• The ability of an object to remain at rest.

• The force that opposes the motion of an object.

• The speed of an object in a straight line.
