Chapter 4: Dynamics II: Forces
Newton's First law
Definition: Every object will continue in its state of rest or uniform motion in a straight line unless a resultant force acts on it
Related to inertia
which is the property of a body which resists change in motion
Quantified by mass of the object (ie if the greater the mass of the object, the greater the inertia
Newton's Second law
When a resultant force acts on an object will accelerate in the direction of the reusultant
Applies to
Balanced forces
Moving at a constant velocity
At rest
Unbalanced forces
Accelerating
Decelerating
F=ma where
F = Resultant Force(N)
m = mass (KG)
a = acceleration (m/s^2)
Newton's Third law
Definition: If body A exerts a force F on Body B, body B will exert an equal and opposite force on body A
Describes Action-reaction pairs
Eg E1 causes C1 which causes E2 that cause C2 which causes E3 to have C3
