Basic Physics Flashcards
The term for the push or pull of an object
Force
The size or strength of the force
Magnitude
The exact location at which a force is applied
Point of application
The straight line passing through the point of application
Line of ACTION
IT is defined as the force transmitted through a rope, string or wire when pulled by forces acting from opposite sides.
Tension Force
It is the force that surfaces exert to prevent solid objects from passing through each other.
Normal force
BALANCED forces are:
- equal in magnitude
- have opposite directions
- lie along the SAME line of action
It is the force generated by two surfaces that contact and slide against each other
Frictional force
The sum of all forces acting on an object (that are in the same line of action) is called the ___.
Net force
The property of an object to resist any change in its state of motion.
Inertia
What are Newton’s Laws of Motion IN ORDER?
1.) First Law - LAW OF INERTIA
2.) Second Law - LAW OF ACCELERATION
3.) Third Law - LAW OF INTERACTION (ACTION-REACTION)
What is the exact measure of acceleration due to gravity”?
9.8 m/s^2
What are the two units of force?
N (Newton),
OR
kg . m/s^2
(The dot is for “times”)
What is the unit of work (as well as energy)?
Joule ( J )
