Escape Velocity
The minimum speed required for a ballistic object to escape a massive body's gravitational field without further propulsion.
Classical MechanicsForce
A vector interaction that, when unopposed, alters the state of motion or deforms a physical body.
Classical MechanicsFrequency (Mechanics)
The number of complete vibrational cycles occurring per unit time.
Classical MechanicsFriction
A resistive contact force that opposes relative sliding motion or tendency of motion between surfaces.
Classical MechanicsGravity
The universal attractive force between masses, causing mutual acceleration proportional to mass and inversely proportional to squared…
Classical MechanicsHooke's Law
A law of elasticity stating that restoring force exerted by a spring or elastic material is proportional to its extension or compression…
Classical MechanicsImpulse
The vector quantity defined as the integral of a force over the time interval during which it acts, equal to the net change in momentum.
Classical MechanicsInclined Plane
A simple machine consisting of a flat supporting surface tilted at an angle to the horizontal.
Classical MechanicsInelastic Collision
A collision in which total linear momentum is conserved, but total kinetic energy is not conserved.
Classical MechanicsInertia
The natural resistance of any physical object to any change in its velocity or state of motion.
Classical MechanicsKinetic Energy
The scalar energy an object possesses by virtue of its motion, proportional to its mass and the square of its speed.
Classical MechanicsMaximum Height
The maximum vertical elevation reached by a projectile above its launch level, where vertical velocity momentarily becomes zero.
Classical MechanicsMechanical Advantage
The factor by which a simple machine multiplies input effort force to overcome load resistance.
Classical MechanicsMechanical Energy
The sum of kinetic energy and potential energy in a physical system.
Classical MechanicsMoment of Inertia
A quantitative measure of a body's rotational inertia - its resistance to changes in rotational motion about a given axis.
Classical MechanicsMomentum
A fundamental vector quantity equal to the product of an object's mass and its velocity, representing its quantity of motion.
Classical MechanicsNewton's First Law
The principle that an object remains at rest or continues in uniform motion in a straight line unless acted upon by a net external force.
Classical MechanicsNewton's Second Law
The law stating that net force acting on a body equals the rate of change of its linear momentum, simplified to mass times acceleration for…
Classical MechanicsNewton's Third Law
The law stating that whenever two objects interact, they exert forces on each other that are equal in magnitude and opposite in direction.
Classical MechanicsNon-conservative Force
A force for which work done depends on the specific path taken, dissipating mechanical energy into heat, sound, or internal energy.
Classical MechanicsNormal Force
The perpendicular contact force exerted by a surface on an object pressing against it.
Classical MechanicsOrbital Velocity
The speed required for a body to maintain a stable circular orbit around a primary gravitational mass at a given radius.
Classical MechanicsParallel Axis Theorem
A theorem stating that the moment of inertia about any axis parallel to a centroidal axis equals the centroidal moment of inertia plus mass…
Classical MechanicsPascal's Principle
The principle stating that pressure applied to an enclosed fluid is transmitted undiminished to every portion of the fluid and container…
