|
Newton's second law of motion
|
States that acceleration of an object is the same direction as the net force on the object.
|
|
|
Friction
|
The force that opposes the sliding motion of two surfaces that are touching each other.
|
|
|
Static Friction
|
The frictional force that prevents two surfaces from sliding past each other.
|
|
|
Sliding Friction
|
The frictional force that opposes the motion pf two surfaces sliding past each other.
|
|
|
Air Resistance
|
Opposes the motion of objects that move through air.
|
|
|
Gravity
|
An attractive force between any two objects that depends on the waves of objects and the distance between them.
|
|
|
Weight
|
The graduated force exerted on an object.
|
|
|
Centripetal Acceleration
|
Acceleration toward the center of a curved or circular path.
|
|
|
Centripetal Force
|
The net force exerted toward the center of a curved path.
|
|
|
Newton's third law of motion
|
When one object exerts a force on a second object. Equal in strength, but different in direction.
|
|
|
Mommentum
|
The product of an object's mass and velocity.
|
|
|
Rolling Friction
|
The frictional force between a rolling object and the surface it rolls on.
|
|
|
Air Resistance (2)
|
Causes objects to fall with different accelerations and different speeds.
|
|
|
What are the four basic Forces?
|
Gravitational Forces
Electromagnetic Forces Strong Nuclear Forces Weak Nuclear Forces |
|
|
Gravitational Force
|
Force that pulls down and it is a long ranged force.
|
|
|
Electromagnetic Force
|
The concept of neutrons repelling neutrons and protons repelling protons.
|
|
|
Strong Nuclear Force
|
Short ranged, holds h protons and neutrons together. Also, it's created by the process of exchange between particles, called mesons.
|
|
|
Weak Nuclear Force
|
Basically they're radioactive waves.
