Lesson 1: Force and Motion Flashcards
It is the EQUAL FORCES acting on one object in opposite directions and does NOT change the object in motion
Balanced Force
When there is an UNBALANCE on the forces acting on one Object
Unbalanced Force
It is the SUM of all forces acting on an Object
Net force / Resultant Force
What are the 2 MAIN types of Forces?
- Contact Forces
- Non Contact Forces
Are the Forces wherein Objects TOUCH/CONTACT with each other
Contact Forces
Are the Forces where Objects DO NOT TOUCH/MAKE CONTACT with each other
Non Contact Forces
Non Contact Forces Act over a ZONE / AREA called a_____?
Field
What are the 4 forces that are UNDER Contact Force?
- Normal Force
- Friction Force
- Applied Force
-Frictional Force
It is A force that ACTS AGAINST/OPPOSITE an Object In Contact with which makes the Movement of the Object Slow Down
Friction Force/Friction
It is the force that is APPLIED to an Object by a person or another object
Applied Force
Force that opposes the relative motion / TENDENCY OF SUCH MOTION OF 2 SURFACES in Contact
Frictional Force
{NoteMagkaiba toh sa Friction/Friction Force since this is about the motion of 2 SURFACES :]]
and not the movement of the object}
A CONTACT FORCE that is perperndicular to the surface that it contacts
Normal Force
This is known as “The push and pull” and what causes an Object to move, move faster, or stop
Force
What are the 3 KNOWN LAWS of Motion?
- Law of Inertia
- Law of Acceleration
- Law of Interaction
According to The Law of Inertia,
“An Object at Rest will __________ and an Object at motion will ________”
-Remain At Rest
-Remain In Motion
True or False: Objects with Greater the Mass have more Inertia
{Ex. A large truck, Bus, Etc.}
True
According to the Law of Acceleration, “The Acceleration of an Object is __________ to the net force, and is __________ to the mass of an Object”
- Directly Proportional
- Inversely Proportional
What Do we Mean By Directly and Inversely Proportional?
Directly Proportional means when One INCREASES, the Other One INCREASES aswell,
While Inversely Proportional Means When One INCREASES, the Other one DECREASES.
What is the Known Formula for Finding FORCE?
F = ma
Practice:
A car of mass 1,200 kg is accelerating at a rate of
3m/s^2. What is the force exerted on the car?
Given: m = 1200 kg
a = 3m/s^2
F=?
F = ma
F = [1200kg][3m/s^2]
F = 3600 kgm/s^2 or N
F = 3600 N
What are The 2 FORCES under Non Contact Force?
- Gravitational Force
- Magnetic Force
