FLASHCARD QUESTION

Front

Force Noun

[fors]

Back

Force


Any push or pull that causes an object to change its motion, with the SI unit being the Newton (N).

Example: This diagram shows how a force from a compressed spring causes a ball at rest to move, demonstrating that a force is a push or pull that can change an object's motion.

FLASHCARD QUESTION

Front

Inertia Noun

[in-ur-shuh]

Back

Inertia


An object's natural resistance to any change in its state of motion, whether it is at rest or moving.

Example: When the car suddenly stops, the box continues to move forward because of its inertia, its tendency to resist a change in motion.

FLASHCARD QUESTION

Front

Mass Noun

[mas]

Back

Mass


The quantitative measure of an object's inertia, representing the amount of matter contained within it.

Example: This image shows a balance scale comparing a rock and a feather, visually demonstrating that the rock has more mass than the feather.

FLASHCARD QUESTION

Front

Net Force Noun

[net fors]

Back

Net Force


The vector sum of all the individual forces acting on a single object, which determines its acceleration.

Example: This image shows two forces (F1 and F2) pulling a box in the same direction, which add together to create a larger total or net force (FR).

FLASHCARD QUESTION

Front

Friction Noun

[frik-shun]

Back

Friction


A force that opposes the relative motion or the tendency of such motion between two surfaces in contact.

Example: This diagram shows that friction is a force that opposes the push (applied force) on an object, caused by the roughness of surfaces rubbing together.

FLASHCARD QUESTION

Front

Gravity Noun

[grav-i-tee]

Back

Gravity


The universal force of attraction acting between all matter, pulling objects with mass toward one another.

Example: An apple, initially at rest on a branch, is pulled downward by the force of gravity, causing it to accelerate towards the ground.

FLASHCARD QUESTION

Front

Weight Noun

[wayt]

Back

Weight


The force exerted on an object due to gravity, calculated as the product of its mass and gravitational acceleration.

Example: Weight is the force of gravity (g) pulling on an object's mass (m), calculated by W=mg. This force is what a scale measures.
