Forces (STUFF LIKE THAT) Flashcards
What is a force
A push, pull or twist in a particular direction.
What is an unbalanced force
When one force is greater than another
Air Resistance
The force that opposes gravity when an object is falling to the ground
Friction
Is a contact force; occurs when 2 surfaces are in contact with each other.
Gravity
non contact force pulling you down
Magnetism
Non-contact force
Mass
How much matter (solid, liquid and gas) is inside of you
Weight
Measure of the pull of gravity on your mass
Newtons (N)
The unit force is measured in
Terminal Velocity
air has become equal to the force of gravity.
Newtons first law
An object in motion will stay in motion, a object at rest will stay at rest unless acted upon an external unbalanced force
Static Friction
Friction that stops an object from moving
Kinetic Friction
the force that opposes an object from moving
Useful Friction
Friction that is wanted
Unwanted Friction
Friction that is unwanted
