Non-Uniform Motion and Acceleration

A set of flashcards covering key concepts related to non-uniform motion and acceleration.

Non-uniform motion

Motion characterized by changing velocity, which involves acceleration.

Acceleration

The rate of change of velocity; vector quantity measured in m/s².

Acceleration Equation

a = Δv / Δt, where Δ represents change.

Δv

Change in velocity, calculated as final velocity (V2) minus initial velocity (V1).

Velocity (V)

The speed of an object in a specific direction, measured in m/s or km/h.

Time (t)

The duration over which motion occurs, measured in seconds (s).

Vector quantity

A quantity that has both magnitude and direction, such as velocity and acceleration.

Derived unit of acceleration

Measured in meters per second squared (m/s²) or kilometers per hour squared (km/h²).

Slope of a v-t graph

Represents acceleration; a steep slope indicates greater acceleration.

Displacement

The area under a v-t graph; it represents the distance traveled.

Zero slope

Indicates constant velocity where there is no acceleration.

Gravity (g)

The acceleration due to gravity; on Earth it is approximately 9.81 m/s².

Decelerated motion

Motion where the velocity decreases over time, resulting in negative acceleration.

Constant velocity

Motion at a steady speed in a constant direction; indicated by a zero slope.

Experimental value for g

The average acceleration due to gravity measured during an experiment.

Percent Error

A measure of how inaccurate a measurement is, calculated as the difference between approximate and exact values divided by the exact value multiplied by 100.
