Dynamics
Terms, formulas, and an interactive lab: mass and density, and a lab with two forces along a line and their resultant, a cart lab for Newton's laws, a spring lab for Hooke's law, and a block lab for friction, and a lab with two attracting bodies and a body on different planets.
Mass and density
Inertia of bodies, mass as a measure of inertia, density of a substance, finding mass and volume, converting g/cm³ to kg/m³; how density relates to the structure of matter (molecules, lattice, states of matter).
Force. Adding forces. The resultant
Force as a measure of the action of one body on another, measuring force with a dynamometer, the resultant of two forces along one straight line.
Newton's laws
Inertia and inertial frames of reference, Newton's three laws: $a = \dfrac{F}{m}$ and $\vec F_{12} = -\vec F_{21}$.
Elastic force. Hooke's law
Deformation (elastic and plastic), the elastic force, spring stiffness, Hooke's law $F = k\Delta l$.
Friction force
Static and sliding friction, the support reaction force, the coefficient of friction, the law $F_{\text{fr}} = \mu N$.
Force of gravity. Universal gravitation. Weight
The law of universal gravitation $F = G\dfrac{m_1 m_2}{r^2}$, the force of gravity $F = mg$, weight and weightlessness.
