Physics - Forces Flashcards
Forces Definition
A force is a push or pull acting upon an object as a result of its interaction with another object
Force Symbol
F
Force Unit
Newtons (N)
Newton’s First Law of Motion
An object remains stationary or remains in a uniform motion unless acted upon by an external force.
What is Newton’s first law of motion also called?
Law of Inertia
EQUATION
Newton’s Second Law of Motion
F = ma
Force = mass x acceleration
Units for Newton’s second law of motion
Newtons (N) = Kilograms (Kg) x Metres per second squared (m/s^2)
Newtons Third Law of Motion
For every action, there is an equal and opposite reaction
Weight Definition
The force exerted on an object due to gravity
Two types of friction
Static Friction
Kinetic Friction
Friction Definition
A force that opposes the motion of an object.
Definition of Air resistance
A force that opposes the motion of objects that move in the air
ALL BEGIN WITH S
What is air resistance dependant on?
Speed
Surface Area
Shape
