Newton's First Law of Motion
An object in motion will stay in motion, and an object at rest will stay at rest, unless acted upon by an unbalanced force.
An object will always remain at rest unless a force is applied to it.
An object in motion will eventually come to a stop due to friction.
An object will accelerate indefinitely unless acted upon by a force.
Metric length
Centimeter, meter, kilometer.
Millimeter, meter, kilometer.
Inch, foot, yard.
Mile, yard, centimeter.
Momentum (p)
A measure of mass in motion, calculated as p = mv.
The force applied to an object over time.
The energy stored in an object due to its position.
The rate of change of an object's temperature.
Albert Einstein

Famous mathematician known for his work in calculus and geometry.
Inventor of the first practical telephone and pioneer in telecommunications.
Renowned biologist who developed the theory of evolution.
Centripetal force
A force that causes an object to move in a circle (e.g., gravity for satellites).
A force that opposes motion between two surfaces in contact.
A force that acts on an object moving in a straight line.
A force that causes an object to accelerate in the opposite direction of its motion.
Gravity
A force that pulls objects toward each other.
A type of energy that can be harnessed.
A phenomenon that occurs only on Earth.
A measure of the weight of an object.
Friction
A force that opposes motion between two surfaces that are in contact.
A force that accelerates motion between two surfaces that are in contact.
A force that reduces the speed of an object in free fall.
A force that acts perpendicular to the direction of motion.
Terminal Velocity
When the force of air resistance is equal in magnitude and opposite in direction to the force of gravity.
The maximum speed an object can reach when falling through a fluid.
The speed at which an object begins to accelerate downwards.
The speed at which an object stops moving altogether.
Galileo Galilei
Italian astronomer, physicist, and mathematician who was the first to use a telescope to study the stars and explained the motion of falling objects.

Potential Energy (J)
The energy stored in objects according to mass and height (mgh).
The energy of motion measured in joules.
The energy released during a chemical reaction.
The energy stored in a compressed spring.
Net Force
The total weight of an object.
The sum of all forces acting on an object.
The force exerted by gravity on an object.
The force that opposes motion.
Law of Conservation of Momentum
The total momentum of a group of objects remains constant unless acted upon by external forces.
Momentum can be created or destroyed in a closed system.
The momentum of an object is always increasing over time.
Momentum is only conserved in elastic collisions.
