FLASHCARD QUESTION
Front
Linear Momentum Noun
[lin-ee-er moh-men-tuhm]
Back
Linear Momentum
The product of an object's mass and its velocity, representing the quantity of motion an object has in a straight line.
Example: This diagram shows a moving block hitting a stationary one. By comparing the 'Before' and 'After' states, it illustrates the conservation of linear momentum.

FLASHCARD QUESTION
Front
Mass Noun
[mas]
Back
Mass
A measure of the amount of matter in an object and its inherent resistance to acceleration, also known as inertia.
Example: This diagram shows that mass (m) is a scalar quantity that relates the force (F) applied to an object and its resulting acceleration (a).
3.
FLASHCARD QUESTION
Front
Velocity Noun
[vuh-los-i-tee]
Back
Velocity
A vector quantity specifying the rate of change of an object's position, indicating both its speed and direction of motion.
Example: This image shows a car moving at a specific speed (20 m.p.h.) in a specific direction (left), which together define its velocity.

FLASHCARD QUESTION
Front
Frame of Reference Noun
[freym uhv ref-er-uhns]
Back
Frame of Reference
A coordinate system or set of axes used to measure and describe the motion and properties of objects.
Example: An observer on the ground (C) sees the cart moving, but from a frame of reference inside the cart, points A and B are stationary.
5.
FLASHCARD QUESTION
Front
Vector Noun
[vek-ter]
Back
Vector
A physical quantity, such as velocity or force, that is defined by having both a magnitude and a direction.
Example: Forces, like the pull on the box and friction, are shown as arrows. These arrows are vectors because they have both a direction and a magnitude (strength).
6.
FLASHCARD QUESTION
Front
Total Momentum Noun
[toh-tl moh-men-tuhm]
Back
Total Momentum
The vector sum of the individual momenta of all the objects that are contained within a defined system.
Example: This diagram shows that the total momentum of a system of objects, like these two balls, remains the same before and after they collide.
7.
FLASHCARD QUESTION
Front
Center of Mass Noun
[sen-ter uhv mas]
Back
Center of Mass
The unique point in an object or system where the weighted average of all mass is considered to be concentrated.
Example: This diagram shows the center of mass (C) for a system of two objects (m1 and m2), which is the average position of all the mass in the system.
