Physics 1D motion

Velocity, Displacement, Acceleration, Free Fall

Frame of reference an object which is used to measure changes in position
Displacement change in position from the starting point
Velocity the measure of rate of movement of an object. Includes direction of motion.
Average Velocity total displacement divided by total time. (includes direction)
Average Speed distance traveled divided by total time. (does not include direction)
Slope rise over run on a graph. Divide the change in the y coordinates by the change in the x coordinates
Instantaneous Velocity velocity of an object at a certain moment in time.
Instantaneous Speed the number given to you by your car’s speedometer.
Acceleration Rate at which velocity changes over time. Can be positive or negative. It is determined by a change in speed, direction, or both.
Free Fall Motion of a body when the only force acting on it is gravity.
Air Resistance Friction created by air that slows the acceleration of an object in free fall.
Terminal Velocity The constant speed an object reaches when falling through a medium. It does depend on mass, shape, and size.

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:
