Flashcards
Velocity
Speed with direction.
Acceleration
Rate of change of velocity.
Force
A push or pull (Newton).
Mass
Amount of matter in an object (kg).
Weight
Gravitational force on a mass.
Inertia
Tendency to resist changes in motion.
Momentum
Mass × velocity.
Work
Force × displacement in the force direction.
Kinetic energy
Energy of motion (½mv²).
Potential energy
Stored energy due to position or configuration.
Friction
Force opposing relative motion between surfaces.
Newton's 1st law
Object stays at rest/uniform motion unless a net force acts.
Newton's 3rd law
For every action there is an equal opposite reaction.
