Force and motion Flashcards
What are some vector quantities
Force Weight Velocity acceleration Momentum Displacement
What’s acceleration
Change in velocity over time
What’s uniform acceleration
Constant acceleration
Acceleration =
Change in velocity /time
Distance traveled =
Speed ❌time
What was Newton’s 1 law
That an object with no net force acting on it moves with constant velocity in a straight line
What’s Newton’s 2 law
The acceleration of an object is directly proportional to the net force on the object
Resultant force =
Mass❌Acceleration
What is mass
Amount of stuff on an object
What is weight
Force acting upon an object
Weight =
Mass❌Gravitational field strength
Momentum =
Mass ❌velocity
What is acceleration
Change in velocity over time
What is Newton’s 3 law
Every action there is an equal and opposite reaction
Force=
Change in momentum /time
