Forces Flashcards
What is a force?
& what is the units?
An action which causes acceleration which is a change in motion
Newtons
What is vector addition for?
Determines overall (net) force
Balanced Force
2 forces acting in a opposide direction with the same magnitude
therefore, it has 0 net force
What is air resistance (drag)?
Acts in opposite direction to a person’s weight
What is inertia?
proportional to mass
the tendency for an object to remain at rest/constant velocity to stay the same until an unbalanced force affects it
Force and acceleration are…
directly proportional
Acceleration and mass are…
inversely proportional
Acceleration and mass are…
inversely proportional
What is mass?
and its units?
Amount of matter
kg
What is weight?
and its units?
mass x gravitational field of something
N
What Newton’s 3rd Law?
For every action there is an equal and opposite reaction
