Forces
What is the basic definition of force?
The push or pull on an object
The force from a surface that pushes upward on an object
Normal/Support Force
Defined as the physical quantity with only magnitude and no direction
Scalar Quantities
What is a NET FORCE?
The total sum of all individual forces acting on an object
A girl pushes a chair with a 5 N force to the east, while friction slows it with a force of 2 N.
Net Force = 3 N, east
Forces that occurs even it is not in contact with another object
Non-contact Forces
A pulling force through a rope, string, or a cable
Tension Force
Defined as the physical quantity that has both directions and magnitude
Vector Quantities
Formula for Net Force acting on same direction
Fnet = F + F
Three students are pushing a table to the west with a force of 37 N each.
Fnet = 111 N, west
Forces that occurs when two objects are interacting to each other
Contact Forces
Force that opposes the motion when two surfaces slide against each other.
Frictional Force
What are the Force Symbol of the following:
Gravitational Force, Normal/Support Force
Fg and FN
Formula for Forces acting on a different/opposite directions
Fnet = F - F
Adam is pulling the box using a rope with a force of 138 N to the east, while Jian is pulling it with a force of 48 N to the west, and Yuan is helping Jian to pull it with a force of 23 N. What is the total Net force?
This are the basic force of nature that results from that results from the simplest interactions between two objects
Fundamental Forces
A force that you exert by pushing or pulling an object
Applied force
What are the Force Symbol of the following:
Friction Force and Applied Force
Ff and Fapplied or Fapp
Forces are balanced when the NET FORCE is equal to what?
A boy pushes the box upwards with a force of 156 N, while the gravity pulls it down with a force of 93 N
Fnet = 63 N, upwards
Forces that are also known as derived forces. It arises from the interactions brought by the four fundamental forces
Non-Fundamental Forces
The pull of the Earth that keeps object on the ground
Gravitational Force
The Force Symbol of Tension Force
FT
How do you consider a force unbalanced?
When the NET FORCE is greater than 1
A car is being pushed upward by the normal force with a 500 N Force, while gravity is pulling it down with the same force as normal force. Then the car applied a force of 320 N to accelerates westward and the road pavements keep it from sliding to much with a force of 137 N.
Fnet = 183 N, westward
