Dynamics and Kinematics Overview

These flashcards cover core concepts from the lecture on dynamics and kinematics, focusing on definitions and key terms essential for understanding motion and forces.

Dynamics

The branch of mechanics that deals with the motion of bodies under the action of forces and momentum.

Mass

The quantitative measure of the inertia or resistance to change in motion of a body; also, the quantity of matter in a body.

Force

The vector action of one body on another.

Particle

An object of negligible dimensions, treated as such when its size is irrelevant to motion and force.

Rigid Body

An object whose changes in shape are negligible compared to its overall dimensions or motion.

Kinematics

A branch of dynamics that describes motion without reference to the forces causing it.

Translational Motion

Motion where an object moves along a line without rotation.

Rotational Motion

Motion involving the rotation of an object around an axis.

Velocity

The rate of change of position of an object in a specific direction.

Acceleration

The rate of change of velocity of an object.

Mass Moment of Inertia

A measure of an object's resistance to changes in its rotational motion.

Rectilinear Motion

One-dimensional motion along a straight line.

Average Velocity

The total displacement divided by the total time taken.

Instantaneous Velocity

The velocity of an object at a specific moment in time.

Gravity

The force of attraction between objects, commonly referred to as the weight of an object.

Units of Force

Commonly measured in newtons (N) or pounds-force (lbf).

Integration

A mathematical process used to calculate areas under curves, often used to solve problems in motion.
