What is the difference between a scalar quantity and a vector quantity?
|
scalar = based on amount (distance) only
vector = includes amount and direction |
|
What is the difference between distance and displacement?
|
distance = how far an object has traveled
displacement = how far an object is from its original position |
|
What is the difference between speed and velocity?
|
Speed = amount of distance traveled in a specific amount of time. Speed is a scalar quantity
Velocity = speed plus direction. Velocity is a vector quantity (based on distance only). |
|
What is acceleration?
|
when an object is speeding up, slowing down, or changing direction. When it's speeding up, it is accelerating in same direction as its velocity (positive acceleration)
|
|
What is deceleration?
|
negative acceleration, or slowing down
|
|
What units do I use for distance:
|
meters
|
|
What units do I use for displacement:
|
meters
|
|
What units do I use for speed:
|
meters per second (m/s)
|
|
What units do I use for velocity:
|
meters per second (m/s)
|
|
What does it mean to say an object is in motion?
|
when its distance from another stationary object is changing (that other object is a reference point)
|
|
What is the calculation for speed?
|
speed = (distance) / (time) OR
s = d / t |
|
What is the calculation for acceleration?
|
acceleration = (final velocity - initial velocity) / time OR
a = (Vf - Vi) / t |
|
What is kinematics?
|
The study of motion
|
|
What are the five components to motion?
|
Distance, Displacement, Speed, Velocity, Acceleration
