Terms

copy deck
- Acceleration
- The rate at which speed and direction of an object changes with time
- England
- Newton's birth place
- 6 billion billion tons
- weight of the earth
- Mass
- Amount of matter in an object or a measure of the inertia of an object
- Sir Isaac Newton's birthday
- 1642 Christmas Day
- Newton's Second Law
- Force is equal to the change in momentum per change in time. For a constant mass, force equal mass times acceleration. F=ma
- Balanced force
- A push or pull acting on the same body, equal in size but opposite in direction
- Newton's First Law
- Every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change that stsate by forces impressed on it
- Velocity
- Speed of a moving object in a specific direction
- Newton's Third Law
- For every action, there is an equal and opposite reaction
- Weight
- Measure of gravitational attraction or force or gravity pulling one object toward the center of another object
- Gravity
- The force that pulls on objects and causes acceleration if the objects are not balanced by an opposing force
- Force
- pressure exerted upon an object; a push or pull
- 1665
- Great Plague swept London so Isaac Newton had to escape to the country
- Motion
- The result of unbalanced forces
- Unbalanced force
- A push or pull acting on the same body, unequal in size and/or opposite in direction -- results in motion
- Traction
- A push or pull that opposes motion between a body and the surface on which it moves, enabling the body to move without slipping
- Speed
- Distance traveled per unit of time
- Friction
- Force that opposes motion between two surfaces
- Inertia
- Resistance to change
