Grade 7 Physics - Advanced Flashcards (UAE MOE)

A collection of vocabulary flashcards covering key concepts from Grade 7 Physics, including position, motion, forces, acceleration, and gravity.

Distance

The total length of the path traveled by an object.

Displacement

The change in position of an object; a vector quantity.

Reference Point

A point used for comparison when determining the position or motion of an object.

Acceleration

The rate at which velocity changes with time; can include changes in speed or direction.

Net Force

The sum of all forces acting on an object.

Newton's Second Law

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass: F = ma.

Friction

A force that opposes motion between two surfaces that are in contact.

Newton's Third Law

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

Gravitational Force

The force of attraction between all objects in the universe with mass.

Free Fall

The motion of an object when the only force acting on it is gravity.

Air Resistance

The force exerted by air on a moving object; it opposes the motion of the object.
