TEK 8.6
Law of Inertia
An object at rest stays at rest and an object in motion stays in motion IN A STRAIGHT LINE unless acted upon by an unbalanced force
Law of Force and Acceleration
F = m x a
Force (N)
Mass (kg)
Acceleration (m/s2)
Law of Action/Reaction
For every action force there is an equal and opposite reaction force
Inertia
Tendency of an object to resist change
Slope
The rate of change of a line
Speed
Distance divided by time
s = d/t
Velocity
Speed with a direction
Acceleration
The rate of change of velocity over time
A = [V(final) - V(start)] / time
Net Force
Comparison of forces acting on an object
Forces in the same direction = add forces
Forces in the opposite direction = subtract forces
Balanced Forces
Net force = 0
NO MOTION
Unbalanced Forces
Net force has a value
MOTION
Position
Location of an object
Direction
The line along which an object moves
Motion
movement of an object due to unbalanced forces
Newtons (unit)
unit of measurement for Force
