Also known as law of inertia
An force is balanced when the forces acting upon an object are of equal magnitude in opposite directions.
A force is unbalanced when the forces acting upon an object are of unequal magnitudes.
Objects will keep doing what they are already doing unless acted upon by an unbalanced force
Objects at rest will stay at rest
Moving objects will continue to move
Forces
A force is a push or pull on an object due to the object’s interaction with another object.
Force is always the result of some sort of interaction
A contact force occurs when two objects are physically touching each other.
An action at a distance force is when two interacting objects do not touch each other, but still exert a force.
For example a person kicking a soccer ball
Gravitational pull is an example of this
Forces are measured in Newtons
1 N= 1 kg*m/s/s
Force is a vector quantity
This means it has both magnitude and direction
You can represent forces with vector diagrams where the size and direction of an arrow demonstrates the size and magnitude of the force.
There are several types of forces
These include:
Frictional Force
Gravitational Force
Tension Force
Electrical Force
Normal Force
Magnetic Force
Air Resistance Force
Applied Force
Spring Force
States that acceleration of an object is dependent on the net force and the mass of the object.
Acceleration depends directly on net force, and inversely on mass
As the net force increases, the acceleration increases. As the mass increases, the acceleration decreases.
This can be expressed through the equation F= ma
Net Force= mass*acceleration
States that for every action there´s an equal and opposite reaction.
The force exerted on one object is equal to the amount of force exerted on the other object
For example, the Earth applies the same amount of force to the moon as the moon applies to the Earth.
Forces come in pairs
<----- Looks like this in a free body diagram
The resistance that is experienced as you push through a fluid
Can be static (μv)
On a flat surface Fn=Fg
Or kinetic (μk)
When applying for to an object, coefficients are the ratio of the weight (Fg) necessary to start or maintain motion
Fg=mg
μ=Fa/Fg
μ=Ff/Fn
When calculating friction, remember that there is a chance the object will not move at all
To make sure that object moves use Fnet= ma
Drag equation: Fd=1/2DV squared Cd*Asx
D= density (kg= m cubed)
V= velocity (m/s)
Cd= Coefficient of drag
Determined by shape and can be googled
Axs= Cross sectional area perpendicular to the direction of motion.
Remember a= πr squared
