NEWTONS LAW Flashcards
(9 cards)
What is NEWTONS 1ST LAW and EXPLAIN
Inertia
- object at rest remains at rest (STATIC EQUILIBRIUM)
- NOT AT REST UNLESS THERES EXTERNAL FORCE OR SOMETHING MOVING IT
what is Dynamic Equilibrium?
object moving in constant velocity continues to move with its constant velocity.
What is Resultant Force?
total force / resultant force that is acting on it is 0.
mass is the measure of?
Inertia
What is NEWTONS 2ND LAW and EXPLAIN
Acceleration
- TOTAL FORCE ACTING on object.
- GREATER MASS, GREATER FORCE
- THE SPEED
in acceleration, its directly proportional to? and inversely proportional to?
Directly Proportional to FORCE
Inversely Proportional to MASS
Formula for Acceleration and its labels
Fnet= ma
Fnet: N
m: kg
a: m/s^2
what is net force (Fnet) ?
vector sum of all forces
What is NEWTONS 3RD LAW and EXPLAIN, give an example
Interaction
- for every ACTION FORCE, there’s EQUAL & OPPOSITE REACTION FORCE
- EQUAL EFFECTS
ex: slapping a person. if u slap a person, he/ she feels the pain as well as the hand.
