Physics in Daily Life Flashcards

A set of vocabulary flashcards covering basic physics concepts, translational and rotational motion, and linear and angular quantities.

Physics

The study of Matter, Energy, Motion, Forces, and Interactions in the universe used to understand the laws of nature.

Force

A push or pull acting on an object, such as pushing a shopping cart.

Motion

The change in position of an object over time.

Energy

The ability to do work, such as electricity powering appliances.

Friction

The force that opposes motion, for example, shoes gripping the floor.

Gravity

The force pulling objects downward, such as seen in falling objects.

Momentum

Measured as how much "moving power" an object has, depending on how heavy the object is and how fast it is going.

Impulse

The change in momentum, representing the amount of "stopping work" that needs to be done.

Force Absorption

The process of stretching out the time it takes to stop to ensure a Low Force is felt.

Translational Motion

Movement where every point of an object moves the same distance, in the same direction, and at the same time without any rotation.

Linear Quantities

Physical properties that describe motion, force, mass, or energy along a straight-line path in a single dimension.

Linear Displacement

A vector quantity defined as the shortest, straight-line distance from an object's initial position to its final position, including direction.

Linear Velocity

A vector quantity that measures the rate at which an object changes its linear displacement over time.

Linear Acceleration

A vector quantity measuring the rate at which an object's linear velocity changes over time, including speeding up, slowing down, or changing direction.

Rotational Motion

The motion of a body spinning about a fixed internal axis.

Angular Displacement

The angle through which an object rotates, measured in radians.

Angular Velocity

The rate of change of angular displacement over time, such as the movement seen on a motorcycle speedometer.

Angular Acceleration

The rate at which the spin speed of an object increases or decreases.

Linear Velocity (v)

The measure of how fast an object travels a distance in a straight line.

Angular Velocity ($\omega$)

The measure of how fast an object completes a turn.

Linear Acceleration ($a$)

The rate of change in an object's straight-line speed.

Angular Acceleration ($\alpha$)

The rate of change in the speed of an object's spin.
