Force — definition?
A push or pull resulting from interaction.
Motion — role?
Describes change in an object's position over time.
Displacement — difference?
Straight-line distance and direction from start to end.
Velocity — what?
Rate of change of displacement; includes speed and direction.
Acceleration — meaning?
Rate at which velocity changes over time.
Newton's First Law — states?
An object remains at rest or in uniform motion unless acted upon.
Newton's Second Law — formula?
Force equals mass times acceleration (F=ma).
Newton's Third Law — principle?
Every action has an equal and opposite reaction.
Friction — types?
Static (preventing motion) and kinetic (opposing moving surfaces).
Gravity — force?
Attractive force between masses, proportional to their product.
