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 personās 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 areā¦
directly proportional
Acceleration and mass areā¦
inversely proportional
Acceleration and mass areā¦
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 Newtonās 3rd Law?
For every action there is an equal and opposite reaction
