Lesson 1 Forces Flashcards
The gap between the initial position and the final position of an object.
Displacement
The speed at which something moves in one direction.
Velocity
The time rate of change of the velocity of an object.
Acceleration
Characterized by push and pull applied to an object.
Force
Influence that changes the motion of an object.
Present even of an object is not moving.
Cause of motions and movements we see everyday.
Force
Refers to how strong the force is, hence the greater the magnitude the faster the velocity.
Magnitude
Measure of magnitude in MKS or the meter kilogram second system
Newton (N)
Measure of magnitude in CGS or centimeter gram second system
Dyne (DYN)
Measure of magnitude in FPS or foot town second system
Pound (LBS)
What system is the international system unit that is mostly used in measuring magnitude
Newton (N)
Newton is the international system unit named after a physicist in mathematician _____
Isaac Newton
Point to where the object goes are going to.
Direction
Where your applying the force
Point of application
Straight line passing through the point of application and is parallel to the direction of the force
Line of action
A type of force wherein an object needs physical contact to another object
Contact Forces
Refers to the force exerted by a person or an object towards another person or object. A type of contact force.
Applied force (F the symbol of Force, Applied Force)
Refers to the force that acts opposite or against another object. A type of contact force.
Friction force denoted by the symbol F’F (the second F is a little one F sub F)
The force that acts perpendicular to an object. Upward force. Supports the/an object as surface resists compression.
Normal force ( F’N)
The force applied to a string rope chain cable and the like. Resists force that causes object to stretch.
Tension force (F’T)
A type of force where objects do not touch or are not in contact with each other.
Non-Contact Forces
The force that attracts object towards the earth. Downward force.
Gravitational force
The force that is exerted on what we call a field of attraction or repulsion takes place between a magnet or a magnetic material.
Magnetic force
In magnetic force it has two poles N and S.Tell if No attraction or attraction.
<—— S|N N|S ——> ______
<—— S|N S|N ——> ______
No Attraction
Attraction
Are those which are at opposite directions and equal in magnitude
Balanced Forces
