1D 2D Physics Vocab

Practice Kinematic vocab for the first common assessment

TermDefinition
magnitude the size of a measurement, a number with a unit
scalar a measurement that only has a magnitude, does not have direction
vector a measurement that has a magnitude and a direction
component a horizontal or vertical part of a resultant vector
resultant the combination of 2 or more vectors into one
displacement vector measurment of how far an object moved from start to finish in a straight line
acceleration speed up, slow down, or change direction
acceleration the rate of change of velocity
velocity the rate of change of position
acceleration due to gravity the rate at which all things fall on the earth
range horizontal displacement of a projectile
projectile object moving only due to gravity
speed scalar, how fast
distance scalar, how far
west, south, down, left negative directions
north, east, up, right positive directions
pythagorean and tan-1 used to find the magnitude and direction of a resultant vector
SOH CAH TOA used to find the components of an angled vector (hypoteneuse)
trajectory the path that a projectile follows, shaped like a parabola
velocity slope on a position time graph
acceleration a curved line on a position time graph
m/s² acceleration unit
m/s velocity unit
m displacement unit
s time unit
a and g acceleration variables
x and y displacement variables
Vx, Vy, Vi, and Vf velocity variables
horizontal component of a projectile that has a constant velocity
vertical component of a projectile that is accelerated due to gravity

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
