Forces Flashcards
a force is a
push or pull
forces are
why objects move or why they don’t move at all
types or forces are
Upthrust, air resistance, gravity, friction, contact, applied
forces can change
The speed, direction and shape
contact forces happen when
two objects are physically in contact with each other
Non-contact forces happen
at a distance and the objects do not need to be in contact with each other
if it is a balanced force
The object will not move
mass is measured in
kg
mass is how much
material is in the object
Mass will always
BE THE SAME
Weight is measured in
Newtons
weight is
how much gravity there is pushing down
weight will
Vary depending on how much gravity there is
weight =
mass x acceleration due to gravity
for every action there is
An equal and opposite reaction
upthrust
The force that acts in a liquid, it pushes upwards against the weight
friction
the force that resists the movement on an object
air resistance
The friction created by air when an object moves through it
Applied force
The force applied by an object or person in direct contact
Spring force
The force stored in a spring when it’s compressed
Gravity
the force that attracts any object with mass
Electrical force
The force between two charged objects
Magnetic
The force between two magnetic objects
