Vectors And Scalars Flashcards
Whats dicplacement
A distance without a change in direction, the shortest distance within points
Whats a vector
Physical quantities with size (magnitude) and direction
Whats a scalar
Physical quantities with size but no direction
Whats the difference between displacement and distance
Distance is the length of the path taken by an object whereas displacement is the simply the distance between where the object started and where it ended up
Whats velocity
Velocity is the speed in a given direction
Whats speed
A magnitude of size with no direction
What are vector forces
Acceleration
Force
Distance
Velocity
Weight
What are scalar forces
Mass
Time
Energy
Power
Speed
What does it mean to force something
To put pressure on an object
What is a force
A push or pull action resulting in a object reacting with another object, measured in newtons
If you apply force to an object, what things can happen
Can change shape, size, speed, motion, form
What are contact and non contact forces
Objects are physically touching
Dont require touch to touch to have an interaction
Examples of contact forces
Air resistance
Thrust
Friction
Tention
Examples of non contact forces
Magnetic
Nuclear
Electrostatic
Gravitational
Examples of non contact forces
Magnetic
Nuclear
Electrostatic
Gravitational
