FLASHCARD QUESTION

Front

Impulse Noun

[im-puls]

Back

Impulse


The product of the average force acting on an object and the time interval over which that force is applied.

Example: This icon shows a person applying a force (a push) to an object, which is the cause of an impulse that changes the object's momentum.

FLASHCARD QUESTION

Front

Momentum Noun

[moh-men-tuhm]

Back

Momentum


A quantity of motion of a moving body, measured as the product of its mass and its velocity.

Example: This diagram shows two objects colliding. The total momentum of the objects before the collision is the same as the total momentum after, demonstrating conservation of momentum.

FLASHCARD QUESTION

Front

Impulse-Momentum Theorem Noun

[im-puls moh-men-tuhm thee-uh-rem]

Back

Impulse-Momentum Theorem


The principle stating that the impulse exerted on an object is exactly equal to the change in that object's momentum.

Example: This diagram shows a ball bouncing off a wall, representing a change in momentum. The text explains that a short contact time results in a high impact force.

FLASHCARD QUESTION

Front

Vector Quantity Noun

[vek-ter kwon-ti-tee]

Back

Vector Quantity


A physical quantity, such as force or velocity, that possesses both a magnitude and a specific direction in space.

Example: A vector quantity, like the forces shown, has both a size (magnitude) and a direction, which can be represented by arrows.

FLASHCARD QUESTION

Front

Change in Momentum Noun

[cheynj in moh-men-tuhm]

Back

Change in Momentum


The difference between an object's final momentum and its initial momentum, often represented by the symbol Δp (delta p).

Example: When the ball is released, the force of gravity acts on it, causing its velocity to increase and therefore changing its momentum from zero.

FLASHCARD QUESTION

Front

Newton-second (N·s) Noun

[noo-tun sek-uhnd]

Back

Newton-second (N·s)


The standard international (SI) unit of impulse, derived from multiplying the unit of force (Newton) by time (second).

Example: This diagram shows that the unit for impulse, the Newton-second (N·s), is equivalent to the unit for momentum (kg·m/s) by breaking it down into fundamental units.

FLASHCARD QUESTION

Front

Force Noun

[fors]

Back

Force


An external influence, such as a push or a pull, that can cause an object to change its motion.

Example: A person pushing a box demonstrates an applied force, while the opposing friction force resists the motion. This shows how forces can act on an object.
