NOTATION
Quantities in formulas
- Force is a measure of the interaction of bodies that changes their movement or shape.
- Mass is a scalar physical quantity that is a measure of the inertia of a body.
- Acceleration is the rate of change in the speed of a body.
- Elastic force is a force that occurs when a body deforms.
- The stiffness of a spring is a characteristic of its resistance to deformation.
- Elongation is a change in the length of a body during deformation.
- Friction force is a force that prevents the relative movement of surfaces.
- Friction coefficient is a characteristic of the resistance to movement of contacting surfaces.
- The support reaction force (normal pressure force) is the force with which the support acts on the body perpendicular to the surface.
- Gravity acceleration is the acceleration of a body under the influence of gravity without taking into account the resistance of the medium.
- Angle is a quantity characterizing the mutual rotation of directions.
- Gravitational constant is a coefficient characterizing the force of universal gravity.
- The mass of the first body is a measure of the inertia of the first body under consideration.
- The mass of the second body is a measure of the inertia of the second body under consideration.
- Distance - the length of the space between selected points.
- Ampere force is the force of a magnetic field on a current-carrying conductor.
- Current strength is the charge passing through the cross section of a conductor per unit time.
- Conductor length is the length of the conductor section under consideration.
- Magnetic induction is a force characteristic of a magnetic field.
- The Lorentz force is a force acting on a moving charge in a magnetic field.
- Electric charge is a quantity that determines the participation of a body in electrical interaction.
- Speed is the speed and direction of change in body position.
