|
It states that an object remains in its state of rest or of motion in a straight line at constant speed unless it is compelled to change that state by forces exerted upon it. |
Law of Inertia |
|
|
is the property of an object to resist change in its current state. |
Inertia
|
|
|
It states that the acceleration produced by a net force on an object is directly proportional to the magnitude of the net force acting on an object and inversely proportional to the mass of an object. |
Law of Acceleration |
|
|
Means we are dealing with an equivalent unbalanced forces. If we add up all the forces (vector addition), the resultant vector is the ___. |
Net Force |
|
|
Exist if a net force applied on an object causes it to accelerate. |
Unbalanced Forces |
|
|
a change in velocity implies that a body undergoes an ___. |
acceleration |
|
|
It states that whenever one body exerts a force (action)on a second body, the second body exerts an equal and opposite force (reaction) on the first. |
Law of Interaction |
|
|
An analysis of the forces acting on object that are at rest or moving with constant speed in straight path is called ___. |
statics |
|
|
Object at rest are at ___ while objects moving in a straight path at constant speed are at ___. |
static equilibrium dynamic equilibrium |
|
|
states that if an object is in translational equilibrium, then the resultant of all forces acting on it must be zero. |
FIRST CONDITION EQUILIBRIUM |
|
|
states that the net torque acting on the object must be zero. |
SECOND CONDITION OF EQUILIBRIUM |
|
|
is defined as the perpendicular distance from the axis of rotation to the line of action of the force. |
Lever Arm |
|
|
is the point at which the body balance. |
Fulcrum or center of mass |
|
|
the fulcrum is between the load and the line of action. |
First Class Lever |
|
|
the load is between the fulcrum and the applied force. |
Second class lever |
