Motion and Force Flashcards
Sir Issac Newton
Born- 12/25/1643
Died - 3/31/1727
Developed Laws of Motion, discovered gravity & moons of Jupiter, famous mathematician
Newton’s 1st Law
an object at rest, stays at rest unless a unbalanced force acts upon it, and at motion, stays in motion with the same speed unless acted on by a unbalanced force
Inertia
the tendency to do nothing or remain unchanged
Newton’s 2nd Law
force = mass + acceleration, the greater the mass, the greater the amount of force needed
Newton’s 3rd Law
every action has an equal and opposite reaction
force
a push or a pull of an object
balanced force
two forces acting in opposite directions of an object
unbalanced force
causes change in motion of an object
Net force
the combination of all forces on an object
friction
a force that causes a moving object to slow down when it touches another object
speed
a way of measuring how quickly something is moving or being done
velocity
the rate at which an object changes positions in a specific direction
Acceleration
The rate at which an object changes its speed or direction
Applied force
a force that is applied to an object by a person or another object
F=M+A
force=mass+acceleration
mass=force/acceleration
acceleration=force/mass
