Kinematics and Dynamics Lecture Notes

A comprehensive set of flashcards covering key concepts of kinematics and dynamics from the lecture notes.

Uniform Motion

Motion where an object covers equal distances in equal intervals of time.

Acceleration

The rate of change of velocity of an object.

Vector Quantity

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

Scalar Quantity

A quantity that has magnitude only, without direction, such as distance or speed.

SI Units

The International System of Units used universally for measurements.

Displacement

The overall change in position of an object, taking direction into account.

Velocity

The speed of an object in a specified direction.

Newton's First Law of Motion

An object at rest will remain at rest, and an object in motion will remain in motion at constant velocity unless acted on by a net external force.

Net Force

The overall force acting on an object, calculated by vector addition of all individual forces.

Equilibrium

A state where all forces acting on an object are balanced, resulting in a net force of zero.

SUVAT Equations

A set of equations used in kinematics to relate displacement, initial and final velocity, acceleration, and time.

Relative Motion

The motion of an object as observed from a specific frame of reference, which may vary depending on the observer's motion.

Friction

The resistive force encountered by an object moving in contact with another surface.

Kinetic Friction

The force that opposes the motion of two surfaces sliding past each other.

Static Friction

The force that must be overcome to start moving an object at rest.

Bearing

The direction or position of an object, measured clockwise from North.

Vector Addition

The process of combining two or more vectors to determine a resultant vector.

Graphical Representation of Motion

Using graphs to show and analyze the relationship between displacement, velocity, and time.

Contact Forces

Forces that occur between objects in direct physical contact, influencing their motion.

Field Forces

Forces that act at a distance, such as gravitational, magnetic, or electrostatic forces.

Velocity-Time Graph

A graph that represents an object's velocity over a period of time.
